Short answer: US permanent residents must keep the United States as their main home. An absence over a year (or a pattern of living abroad) can be treated as abandonment. For long trips, apply for a re-entry permit and keep US ties.
Risk signals
- Continuous absence near or over one year
- Fixed home, job and tax centre abroad
- No US home, tax filings or real ties
Practical tips
- Apply for a re-entry permit before long absences
- Keep US housing, banking and tax records
- Align naturalisation plans with days of presence
Individual cases need immigration counsel.
