U.S. immigration law offers four main ways to be lawfully present in the country on a temporary basis: nonimmigrant visas, Temporary Protected Status (TPS), humanitarian parole, and asylum. Each has its own eligibility test, its own time limit, and its own rules on working, traveling, and eventually moving toward a green card. They are not interchangeable, and choosing or maintaining the wrong one can end in removal proceedings and a multi-year bar on returning. Recent legislation, especially the One Big Beautiful Bill Act signed into law on July 22, 2025, has changed key features of TPS and asylum, including work permit durations and new fees.
Nonimmigrant Visas: Temporary Entry for a Defined Purpose
Nonimmigrant visas cover people entering the United States for a specific temporary purpose. Federal law presumes every applicant secretly intends to stay permanently, and you have to overcome that presumption by showing a consular officer strong ties to your home country. H-1B and L visa holders, along with their spouses and minor children, are the main exceptions: they can openly pursue a green card while holding temporary status.1Office of the Law Revision Counsel. 8 USC 1184 – Admission of Nonimmigrants
Visitors, Students, and Workers
B-1 visas cover short business trips such as conferences and contract negotiations; B-2 visas cover tourism and medical treatment. The initial stay is up to six months, one extension of up to six more months is possible, and total time on a single trip generally cannot exceed one year.2U.S. Citizenship and Immigration Services. B-1 Temporary Business Visitor
F-1 students must stay enrolled full time at an approved school. The authorized stay covers the length of the academic program plus a 60-day grace period; M-1 vocational students get 30 days.3Study in the States. Maintaining Status Dropping below full-time enrollment or working off campus without authorization ends status immediately. F-1 and M-1 students pay a $350 SEVIS fee before arriving; J-1 exchange visitors pay $220.4U.S. Immigration and Customs Enforcement. I-901 SEVIS Fee
The H-1B is the main visa for jobs that require specialized knowledge and at least a bachelor’s degree.5U.S. Citizenship and Immigration Services. H-1B Specialty Occupations Congress caps it at 65,000 visas per fiscal year, with 20,000 more set aside for people holding a U.S. master’s degree or higher. When registrations exceed those numbers, USCIS runs a weighted lottery favoring higher-wage positions.6U.S. Citizenship and Immigration Services. H-1B Cap Season L-1 visas cover employees transferred within the same company from an overseas office. O-1 visas are for individuals with extraordinary ability in their field.
Most nonimmigrant categories extend derivative status to a spouse and unmarried children under 21: H-4 for H-1B dependents, F-2 for F-1 dependents, and so on. These family members generally cannot work. H-4 spouses are the notable exception, becoming eligible for work authorization if the H-1B principal has an approved immigrant worker petition or an H-1B extension past the six-year limit.7U.S. Citizenship and Immigration Services.

Interviews and the Cost of Overstaying
As of October 2025, the Department of State requires an in-person interview for nearly all nonimmigrant visa applicants. Waivers are narrow, covering certain diplomatic applicants and B-1/B-2 or H-2A renewals filed within 12 months of expiration, generally only if you apply in your country of nationality and have no prior refusals or apparent ineligibility.8U.S. Department of State. Interview Waiver Update Some nationalities also owe a reciprocity fee when the visa is issued, which varies by country and category.9U.S. Department of State – Bureau of Consular Affairs. Fees for Visa Services
Overstaying has hard consequences. Overstay by more than 180 days but less than a year, and you face a three-year bar on reentry. Overstay by a year or more, and the bar becomes ten years.10U.S. Citizenship and Immigration Services. Unlawful Presence and Inadmissibility
Temporary Protected Status
TPS is a country-specific protection. When conditions abroad make it unsafe for nationals to return, the Secretary of Homeland Security can designate that country. The statute recognizes three qualifying situations: ongoing armed conflict that would seriously threaten returning nationals, an environmental disaster that has substantially disrupted living conditions, or other extraordinary and temporary conditions preventing safe return. An environmental disaster designation requires a formal request from the foreign government.11Office of the Law Revision Counsel. 8 USC 1254a – Temporary Protected Status
To qualify, you must be a national of the designated country (or stateless and last a resident there), register during the announced window, and show continuous presence and residence in the United States since the dates the Secretary specifies. A felony conviction, or two or more misdemeanors in the United States, makes you ineligible, as do certain security-related bars.12U.S. Citizenship and Immigration Services. Temporary Protected Status
TPS shields you from removal and makes you eligible for a work permit. It does not lead to a green card on its own, though it also does not stop you from pursuing one through another channel if you qualify. TPS holders can request travel authorization to leave and return.
What Changed in 2025
The One Big Beautiful Bill Act shortened TPS work permits. They are now limited to one year or the remaining length of the TPS designation, whichever is shorter.13U.S. Citizenship and Immigration Services. DHS Announces Consequences for Unpaid Annual Asylum Fees, Unveils New HR 1 Requirements The previously available 540-day automatic extension for renewal applications has been cut back. For renewals filed after July 22, 2025, the automatic extension is capped at one year or the length of the designation, whichever is shorter, even when the receipt notice lists a longer period.14U.S. Citizenship and Immigration Services. Update to TPS Page on EAD Automatic Extensions Renewals with a received date of July 21, 2025, or earlier keep the longer extension, but any portion running past July 22 cannot last more than one year from that date.
Humanitarian Parole
Parole is a discretionary tool that lets DHS allow someone into the country on a case-by-case basis for urgent humanitarian reasons or significant public benefit. The critical thing to understand is that parole is not a formal admission. You are physically present, but you have not been legally “admitted” the way a visa holder or permanent resident has been.15Office of the Law Revision Counsel. 8 USC 1182 – Inadmissible Aliens That difference affects what you can do next, including whether you can adjust to permanent residence.
Humanitarian parole typically covers life-threatening situations or urgent family circumstances: specialized medical treatment only available here, visiting a terminally ill relative, or attending a close family member’s funeral. These requests require substantial documentation, such as medical records or death certificates. Significant public benefit parole serves a different purpose, often bringing in a witness for a criminal trial or someone participating in a government investigation. Parole lasts only as long as needed for that purpose.
Parolees can apply for work authorization while present, but parole itself is not a path to permanent status. When it expires and is not renewed, you revert to any prior status or become subject to removal.
Traveling Is Risky Even With Advance Parole
Leaving the country as a parolee is legally risky even with an advance parole document. Parole granted under the humanitarian or public benefit provision automatically terminates on departure, regardless of the document you carry. On return, you are treated as a new applicant for admission and can be denied entry if found inadmissible. DHS can also revoke advance parole at any time, including while you are outside the country.16U.S. Citizenship and Immigration Services. Instructions for Form I-131, Application for Travel Documents, Parole Documents, and Arrival/Departure Records If you have a pending adjustment of status application and leave without advance parole, USCIS generally treats that application as abandoned, though exceptions exist for people in H-1/H-4, L-1/L-2, K-3/K-4, and V status returning with a valid visa.
Asylum
Asylum protects people who face persecution in their home countries. To qualify, you must be physically present in the United States or arriving at a port of entry, and you must establish that you are a refugee: unable or unwilling to return home because of past persecution or a well-founded fear of future persecution.17Office of the Law Revision Counsel. 8 USC 1158 – Asylum That fear must be connected to one of five protected grounds: race, religion, nationality, membership in a particular social group, or political opinion. The persecution must come from the government or from a group the government cannot or will not control.
The Supreme Court held in INS v. Cardoza-Fonseca that “well-founded fear” does not require showing persecution is more likely than not. A reasonable person in your situation just has to have a genuine fear, even if the statistical odds are below 50 percent.
The One-Year Deadline
You generally must file for asylum within one year of your last arrival. Missing the deadline can bar you entirely unless you show changed circumstances that materially affect eligibility, or extraordinary circumstances that prevented timely filing. Changed circumstances include new conditions in your home country, changes in U.S. law, new activities that put you at risk, or the loss of a family relationship to a principal applicant through divorce, death, or a child turning 21. Even with an exception, you must file within a reasonable time after those circumstances arise.
Affirmative and Defensive Filings
If you are not in removal proceedings, you file affirmatively by submitting Form I-589 to USCIS. An asylum officer conducts a non-adversarial interview, and you generally must bring your own interpreter. If the officer does not approve the case and you have no other legal status, USCIS issues a Notice to Appear and refers you to immigration court.18U.S. Citizenship and Immigration Services. Obtaining Asylum in the United States
If you are already in removal proceedings, you file defensively before an immigration judge. This is adversarial, with a government attorney arguing against your claim, and the court provides an interpreter. If the judge denies asylum, they will consider other forms of relief before ordering removal.
Some people are barred from asylum regardless of how strong their persecution claim is: those convicted of a particularly serious crime, deemed a security danger, who participated in persecuting others, or who were firmly resettled in another country before arriving.19U.S. Citizenship and Immigration Services. USCIS Policy Manual Volume 4, Part C, Chapter 3 – Admissibility and Waiver Requirements
Working, and the New Annual Fee
Once asylum is granted, you can work immediately and may apply for a green card after one year in asylee status.20U.S. Citizenship and Immigration Services. Green Card for Asylees While the application is pending, you can file for work authorization 150 days after submitting the asylum application, and you become eligible to actually receive the permit once the application has been pending for 180 days total. Delays you cause or request do not count toward those timelines.21U.S. Citizenship and Immigration Services. Asylum The prior 30-day processing deadline for asylum-based work permits has been removed.
The One Big Beautiful Bill Act introduced new costs. USCIS now charges a filing fee for Form I-589 and an Annual Asylum Fee that must be paid each calendar year the application remains pending. Miss the annual fee by more than 30 days after notification, and USCIS will reject the pending asylum application, deny any pending work authorization request, and revoke any existing work permit. If you have no other legal status, removal proceedings follow.13U.S. Citizenship and Immigration Services. DHS Announces Consequences for Unpaid Annual Asylum Fees, Unveils New HR 1 Requirements Fee amounts adjust for inflation each year, so confirm current figures on the USCIS fee schedule before filing.
When Asylum Is Not Available
Two related protections exist for people who face serious harm abroad but cannot meet asylum’s requirements or are barred from eligibility. Neither leads to a green card.
Withholding of removal blocks the government from sending you to the specific country where you face persecution, but the burden is higher: you must show it is more likely than not that you would be persecuted on account of a protected ground. You cannot travel abroad, cannot petition to bring family members, and have no path to permanent residence or citizenship. The government can also revoke the protection if conditions improve and retains authority to remove you to a different country willing to accept you.
Protection under the Convention Against Torture is available to anyone who can show it is more likely than not that they would be tortured by, or with the consent of, a government official on return. There is no requirement to link the torture to a protected ground, and there are no criminal bars to eligibility.
Changing, Extending, and Reporting
If your situation changes while you are in the United States, you may be able to switch to a different nonimmigrant category or extend your current stay without leaving. To change categories or extend, you generally file Form I-539 before your current authorized stay expires; USCIS recommends filing at least 45 days ahead. You must have been lawfully admitted, not have violated your status, and hold a valid passport covering the requested stay.22U.S. Citizenship and Immigration Services. Application to Extend/Change Nonimmigrant Status If your status has already expired or you worked without authorization, USCIS generally cannot approve the change except in narrow circumstances beyond your control. Certain employment categories, including H-1B, L-1, and O-1, require the employer to file Form I-129 instead.
Adjustment of status is a different process entirely. It is how you apply for a green card while inside the United States, using Form I-485, and typically requires an approved family-based or employment-based immigrant petition.23U.S. Citizenship and Immigration Services. Adjustment of Status
Whatever status you hold, report any change of address to USCIS within 10 days of moving. This applies to every foreign national in the country, with limited exceptions for certain diplomats and visa waiver visitors, and it is a federal legal requirement rather than optional paperwork. Filing online through a USCIS account updates your address almost immediately; a paper Form AR-11 by mail also works.24U.S. Citizenship and Immigration Services. AR-11, Aliens Change of Address Card A missed interview notice or request for evidence because USCIS mailed it to your old address can lead to a denial, and the agency has no duty to track you down.
