This is the question that produces the most avoidable damage in immigration cases. A client has a pending adjustment of status application, a family emergency comes up abroad, and they board a flight. Under the general rule, departing the United States while an I-485 is pending is treated as abandonment of that application — even if the emergency was genuine, even if they come right back.
Advance parole
The mechanism that prevents this is advance parole, requested on Form I-131. It is travel permission tied to your pending application. With an approved advance parole document, you can leave and return without abandoning the I-485. Without it, the general rule applies.
Two timing points matter. First, the document has to be approved before you leave — filing the request is not enough. Processing takes months, so it should be filed at the same time as the I-485 rather than when a trip comes up. Second, you have to return while it is still valid.
What changed in August 2026, and why it matters more than anything else here
Advance parole protects your application from being treated as abandoned. As of August 13, 2026, it no longer protects you from the unlawful presence bars.
For more than a decade, leaving on advance parole was not treated as a “departure” for those bars. The Board of Immigration Appeals changed that in Matter of Delcarmen-Lara, 29 I&N Dec. 830 (BIA 2026), which overruled its earlier decision in Matter of Arrabally and Yerrabelly. USCIS now takes the position that departing the United States after obtaining an advance parole document is a departure for purposes of inadmissibility under section 212(a)(9)(B).
Here is what that means in practice. If you accrued more than 180 days of unlawful presence before filing, and you then leave the country — even on an approved advance parole document, even briefly, even for a funeral — you can trigger a three-year bar on returning. A year or more of unlawful presence can trigger a ten-year bar. The departure itself is what sets the bar running.
So the question is no longer only “do I have advance parole?” It is now also “did I accrue unlawful presence before I filed?” Many people do not know the answer to that second question, and some are wrong about it. If there is any period where you were in the United States without status — an overstay, a gap between filings, entry without inspection — talk to a lawyer before you book a ticket. This is not a situation where travelling first and asking afterwards can be repaired.
The H-1B and L-1 exception
People maintaining valid H-1B or L-1 status, and their dependents in H-4 or L-2, can generally travel on that visa while an I-485 is pending without advance parole, provided they return in the same status and continue working for the sponsoring employer. This is a real exception, but it is narrower than people assume, and it depends on maintaining the underlying status throughout.
Approved travel is not guaranteed entry
Advance parole gets you to the port of entry. It does not oblige an officer to admit you. Anyone with a prior removal order, a criminal history, or an unlawful presence issue should treat re-entry as a real risk and get advice specific to their record before booking anything.
The practical rule
File the travel request with your application, not later. Do not book international travel until the document is in hand. Before you travel, get a clear answer on whether you accrued unlawful presence before filing — since August 2026 that, not the advance parole document, is what decides whether leaving is safe.
