How Does the U.S. Refugee Vetting Process Work?

The US refugee vetting process is the layered security, identity, and eligibility screening that every applicant to the US Refugee Admissions Program (USRAP) goes through before being allowed to travel to the United States. It involves the Department of State, the Department of Homeland Security, the Department of Health and Human Services, and multiple intelligence and law enforcement agencies working in parallel. Under normal operations, the full pipeline from referral to arrival runs roughly 18 to 36 months.¹

One boundary to know up front. For fiscal year 2026, the presidential admissions ceiling is 7,500, and a January 2025 executive order suspended most refugee entry except when the Secretaries of State and Homeland Security jointly approve an admission as being in the national interest.²³ The screening steps below remain the codified process; they describe how vetting works whenever the program is operating.

Getting Into the Pipeline

Vetting doesn’t start with a self-filed application. You cannot apply to the USRAP on your own. A case begins only when someone is formally referred, typically by the United Nations High Commissioner for Refugees, a US embassy, or a designated nongovernmental organization, or through a family reunification filing by a US-based relative already admitted as a refugee or asylee.⁴

To be eligible, the applicant must fit the federal definition of a refugee: someone outside their home country who cannot return because of persecution or a well-founded fear of persecution based on race, religion, nationality, political opinion, or membership in a particular social group.¹ Two bars can knock out an otherwise qualified applicant. Anyone who has participated in persecuting others is permanently disqualified. And a person considered “firmly resettled” in a third country before reaching the United States is ineligible; under 8 CFR 208.15, that can include receiving permanent legal status in a transit country, holding indefinitely renewable status there, or voluntarily residing there for a year or more after fleeing.⁵ Firm resettlement can even be imputed to a child based on a parent’s status.

Security and Background Checks

Screening is where the USRAP earns its reputation as the most intensive entry pathway to the United States. Checks run concurrently across agencies and continue throughout the life of the case rather than at a single point. The participating agencies include DHS, the FBI, the Department of Defense, and the National Counterterrorism Center.¹

Biographic Screening

Resettlement Support Centers collect names, dates of birth, and other identifying data and submit them through the Interagency Check, which routes the information through the National Vetting Center for coordinated review by intelligence and law enforcement partners. The checks look for connections to terrorism, serious crime, and other inadmissibility grounds.¹

Biometric Screening

Applicants provide fingerprints and photographs that are run against biometric holdings at DHS, the FBI, and the Department of Defense. The Defense Department’s database draws from areas of significant US military presence and has covered all refugee nationalities since 2013.¹ Any hit has to be investigated and resolved before the case moves forward.

Social Media Disclosure

Applicants must disclose all social media handles and usernames used over the past five years on Form I-590, the application for refugee classification. That information feeds into identity verification and security vetting. The requirement was formalized following a January 2025 executive order directing enhanced visa vetting and screening.

The USCIS Interview

Once initial security checks clear, the applicant sits for an in-person interview overseas with a trained USCIS officer. This is the legal determination stage. The officer verifies identity, assesses the credibility of the persecution claim, evaluates whether the firm resettlement bar or any other bar applies, reviews the results of the security screening, and decides whether to exercise favorable discretion on the application.¹

If the applicant’s English is limited, the Resettlement Support Center provides an interpreter; the program strongly discourages using other refugees to interpret.⁶ The officer’s decision is not final on its own. A USCIS supervisor reviews approved cases before the approval takes effect, adding a layer meant to catch errors and keep decisions consistent across adjudicators.

Medical Screening and Vaccinations

Conditionally approved applicants undergo a medical examination by a panel physician, a doctor appointed by the local US embassy or consulate who follows technical instructions from the Centers for Disease Control and Prevention.⁷ The exam is designed to identify health conditions that make someone inadmissible under the Immigration and Nationality Act.⁸

Certain communicable diseases automatically render an applicant inadmissible until treated:

Active, communicable tuberculosis
Infectious syphilis
Gonorrhea
Infectious Hansen’s disease (leprosy)

For applicants examined overseas, two broader categories also apply: diseases subject to federal quarantine orders and diseases the CDC determines pose a potential public health emergency of international concern.⁹ HIV is not on the list; it was removed from inadmissible conditions in 2010.⁷

The exam also verifies that the applicant has received vaccinations against diseases specified in the Immigration and Nationality Act, including measles, mumps, rubella, polio, tetanus, diphtheria, pertussis, hepatitis B, and influenza, among others.⁸ Required vaccines depend on the applicant’s age; children under six need polio and Hib vaccines, while adults need Tdap boosters. The CDC’s most recent revision to the vaccination schedule took effect in March 2025.¹⁰ Missing vaccinations don’t permanently block admission, but they have to be administered before the applicant clears the medical stage.

Why Vetted Cases Still Wait

Even applicants who complete every screening step can find themselves stuck. Processing times vary widely based on the applicant’s country of origin, the caseload at the responsible Resettlement Support Center, and the security and infrastructure conditions in the region. Cases with hard-to-verify biographical data or security hits requiring further investigation take longer.

Clearance expirations are one of the most frustrating causes of delay. Security and medical clearances each have a finite validity period. If any step downstream stalls, an earlier clearance can expire and has to be redone, which can push another clearance past its own expiration. Applicants caught in that cycle sometimes wait years beyond the typical 18-to-36-month window.

The annual presidential determination shapes the pace as well. The FY2026 ceiling of 7,500 is a maximum, not a target, and the government has no obligation to fill it.² Fully cleared cases can sit in queue indefinitely.

If the Application Is Denied

There is no formal appeal from a denied refugee application. USCIS will, however, consider a Request for Review (RFR) if submitted within 90 days of the denial notice.¹¹ The RFR has to identify a significant error by the adjudicating officer, present new information that would change the outcome, or both. Only one request is accepted per case.

The principal applicant must sign the RFR, and it goes directly to the Resettlement Support Center that handled the case. If an attorney submits it, Form G-28 (notice of attorney appearance) must be included. USCIS international field offices stopped accepting RFRs in October 2019, so sending to the wrong location means missing the deadline.¹¹ One shot, ninety days, one address.
