How Long Can I Remain Outside the U.S. without Losing My Green Card (Immigrant Status)?
If you are a Green Card holder (lawful permanent resident or conditional permanent resident) and will be outside of the U.S. for more than a year, you will need to make special preparations for your re-entry, before you leave the U.S. See Green Card & Travel Outside the US: Documents and Issues for US Reentry. If you have applied to adjust to permanent resident status, you should be careful of any trip outside the U.S. – see Advance Parole: Foreign Travel with a Pending Green Card Immigration Application.
