영주권자 신분 유지를 위해 몇 개월을 넘으면 안된다, 몇 일은 최소한 미국에 머물러야 한다는 식의 룰은 없습니다 (예외: 재입국허가 없이 1년 이상 해외 체류의 경우 자동으로 abandon한 것으로 판단합니다.)
미국 입국시 심사관이 여러가지 요소를 기반으로 영주의사를 판단합니다. "여러가지 요소가 무엇인지는 이민국 홈페이지에 있으며 (https://www.uscis.gov/green-card/after-green-card-granted/maintaining-permanent-residence) , 아래 해당 부분을 copy and paste 하여 드립니다.
You may also lose your permanent resident status by intentionally abandoning it. You may be found to have abandoned your status if you:
- Move to another country, intending to live there permanently.
- Remain outside of the United States for an extended period of time, unless you intended this to be a temporary absence, as shown by:
The reason for your trip;
How long you intended to be absent from the United States;
Any other circumstances of your absence; and
Any events that may have prolonged your absence.
Note: Obtaining a re-entry permit from USCIS before you leave, or a returning resident visa (SB-1) from a U.S. consulate while abroad, may assist you in showing that you intended only a temporary absence.
- Fail to file income tax returns while living outside of the United States for any period.
- Declare yourself a “nonimmigrant” on your U.S. tax returns.
