A trip of more than 6 months creates a presumption that you broke continuous residence for citizenship, and it can lead to questions at the airport about whether you abandoned your residence. After 1 year outside the U.S., or after your re-entry permit expires, the green card alone is no longer enough to come back. You would need a returning resident (SB-1) visa, which requires showing that the long stay was caused by circumstances beyond your control.
A re-entry permit, requested on Form I-131, can be valid for up to 2 years and lets you return after a long absence. You must be in the U.S. when you file and attend the biometrics appointment. A re-entry permit is a travel document only: it does not protect continuous residence for citizenship. Only an approved Form N-470 does that, and only for certain types of work abroad.
Permanent residence depends on intent as well as time. Living and working abroad, filing U.S. taxes as a nonresident or giving up your U.S. home can suggest abandonment even after a trip of less than 6 months. Keep your U.S. address, bank accounts, tax filings and employment ties, and speak with an attorney before a long stay abroad.
You can, but a trip of more than 6 months creates a presumption of a break in continuous residence for citizenship and can lead to questions about abandonment when you return.
The green card alone is no longer a valid travel document, and continuous residence for citizenship is broken. Without a valid re-entry permit, you would need an SB-1 returning resident visa from a U.S. consulate.
No. A re-entry permit helps you return, but it does not preserve continuous residence for naturalization. Only an approved Form N-470 does, and only for qualifying employment abroad.
Before you leave. You must be physically present in the U.S. when you file Form I-131 and should plan to attend the biometrics appointment before departing.
When can I file Form N-400? Checks the 5-year and 3-year rules, the 90-day early filing window, trips and physical presence.
