Parents visiting on a B-2 visitor visa can generally stay in the United States for up to six months per entry, and that stay can be extended once by up to another six months if they apply on time. The exact departure date is set by a Customs and Border Protection officer when your parent arrives, not by the visa stamp in the passport. Parents who enter under the Visa Waiver Program instead of a B-2 visa are on a much shorter clock: 90 days, with no option to extend.
The Six-Month B-2 Stay and the I-94 Date
When your parent lands at a U.S. port of entry, a CBP officer decides how long they’re allowed to stay. The officer weighs the stated purpose of the visit, financial support, and whether your parent appears likely to leave when the visit ends. Six months is the maximum for a B-2 visitor. It isn’t automatic. The officer can grant less if the reason for the visit doesn’t justify a full six months.
Whatever the officer decides is recorded on Form I-94, the electronic arrival/departure record. Your parent can look up their I-94 on the CBP website and confirm the “Admit Until Date.” 1U.S. Citizenship and Immigration Services. Form I-94, Arrival/Departure Record, Information for Completing USCIS Forms That is the deadline that matters. The visa stamp’s expiration date is a separate thing entirely; it controls when your parent can enter the country, not how long they can stay once inside. If the I-94 says six months and the visa is good for ten years, the six months still governs.
Visa Waiver Program Parents Get 90 Days and Cannot Extend
Not every parent enters on a B-2 visa. Citizens of roughly 40 countries can travel to the U.S. for up to 90 days under the Visa Waiver Program using an ESTA authorization rather than a visa. If that’s how your parent came in, the rules below on extensions do not apply to them.
Visa Waiver Program visitors cannot extend beyond the 90-day admission and cannot change to another immigration status while in the U.S. 2U.S. Department of State. Visa Waiver Program They have to leave on or before the I-94 date. If a parent from a VWP country expects to need more than 90 days, the right move is to apply for an actual B-2 visa at a U.S. consulate before the trip rather than arriving on ESTA and hoping to stretch the stay.
Applying to Extend a B-2 Stay
A parent already in the U.S. on a B-2 visa can ask for more time by filing Form I-539, Application to Extend/Change Nonimmigrant Status. Extensions come in increments of up to six months, so with one approved extension the total stay reaches about a year. Further extension requests are possible after that, but each one draws heavier scrutiny.
To be eligible, your parent needs to meet a few conditions:
- They were lawfully admitted and have not violated the terms of their visitor status.
- Their passport is valid through the full requested extension period.
- They have not done anything that would make them removable or otherwise ineligible.
USCIS recommends filing the I-539 at least 45 days before the I-94 expires. 3U.S. Citizenship and Immigration Services. Extend Your Stay Treat that as the minimum, not the goal. Filing earlier gives more breathing room, since processing can stretch to several months. Form I-539 can be filed online or mailed to the USCIS lockbox. 4U.S. Citizenship and Immigration Services. Form I-539, Application to Extend/Change Nonimmigrant Status The application needs a written explanation of why more time is needed, evidence of financial support, and a proposed new departure date. A support letter from you as the U.S.-based child, bank statements, and proof of health insurance all help the case. Current fees are posted on the USCIS page for the form.
What Happens While the Extension Is Pending
This is where families often get anxious. If the I-539 was filed before the I-94 expired and USCIS hasn’t decided yet, your parent is generally in a period of authorized stay. They are not accruing unlawful presence just because the case is sitting in a queue. That protection lasts as long as the application remains pending.
If USCIS denies the extension, the picture changes fast. Unlawful presence can start accruing from the date of denial, and your parent needs to leave promptly. A denial after the I-94 has already expired is a bad position to be in, which is why filing early and building a solid application matters. Late filings, submitted after the I-94 has passed, can only be excused in extraordinary circumstances beyond the applicant’s control. 5U.S. Citizenship and Immigration Services.

What Overstaying Costs
Staying past the I-94 date without a pending or approved extension sets off consequences that can affect visits for years.
One is automatic. The visa in your parent’s passport becomes void the moment they overstay. 6Office of the Law Revision Counsel. 8 USC 1202 – Application for Visas To come back, they’d have to apply for a new visa at a consulate in their home country, and the prior overstay will be part of that record.
The other consequences scale with how long the overstay lasts:
- More than 180 days but less than one year of unlawful presence, followed by a voluntary departure, triggers a three-year bar on returning.
- One year or more of unlawful presence, followed by departure, triggers a ten-year bar.
These bars are set in federal immigration law and apply regardless of the reason for the overstay. 7Office of the Law Revision Counsel. 8 USC 1182 – Inadmissible Aliens The unlawful presence has to be continuous within a single stay to count toward the 180-day or one-year thresholds.
Long or Repeated Visits Can Create a Tax Problem
Families rarely think about the IRS when a parent visits, but a long stay, or a pattern of long stays, can turn a visitor into a U.S. tax resident. The substantial presence test counts days in the U.S. across a three-year window. If your parent was present at least 31 days in the current year and the weighted total across three years reaches 183 days, the IRS treats them as a resident alien for tax purposes. 8Office of the Law Revision Counsel. 26 USC 7701 – Definitions Days in the current year count fully, days in the prior year count as one-third, and days two years back count as one-sixth. A parent who visits for five or six months every year can cross the line quickly.
Tax residency means the IRS expects reporting of worldwide income, which is a serious obligation for someone who came to see the grandchildren. There is a way out: the closer connection exception. If your parent was in the U.S. fewer than 183 days in the current year and can show that their tax home and stronger personal ties are still abroad, they can avoid U.S. tax residency by filing IRS Form 8840 each year. 9Internal Revenue Service. About Form 8840, Closer Connection Exception Statement for Aliens The exception is not available to anyone who has applied for a green card or taken steps toward permanent residency during that year.
Planning the Next Visit
CBP officers see your parent’s full travel history at the border, and a pattern of maximum stays with short gaps between them raises the question of immigrant intent. Someone who spends ten months a year in the U.S. and two months abroad starts to look less like a visitor.
The counter to that is genuine, documented ties to the home country: property, an active bank account, ongoing employment or pension income, dependents at home, community commitments. A letter from an employer, proof of a lease, or evidence of pension payments carries weight at the port of entry, and your parent should have these ready after any prior long stay.
Spacing matters too. There is no published CBP formula, but a common practical guideline is to spend at least as much time outside the U.S. between visits as was spent inside. A parent who stayed five months should generally wait at least five months before returning. When a family genuinely needs a parent present for longer, such as after a birth or during an illness, one well-documented I-539 extension is usually a safer path than stringing together repeated near-maximum visits.
