I have green card and i been outside america for ten months can i enter america again?
Answer:
Yes, you can. But be prepared to be asked some pointed questions about why you were away for so long, and whether you still are a resident of the US. The absolute maximum is 12 months unless you get a re-entry permit before you leave, but LPRs have been known to have been denied entry earlier than that if it was obvious to the CBP officer that they were entering only to 'stamp themselves in' and keep their green cards while, in fact, living most of their lives outside.
Good luck!
In addition to being prepared to answer questions about why you were absent from the U.S. for so long, if you have any proof to support your absence, you should carry that with you. For example, if you were caring for a sick family member, you should carry any supporting documentation to prove that. You may also be asked for proof that you were maintaining your residence in the U.S. to show that you did not abandon your residency, so any proof that you have such as filed tax returns, house leases, bank statements may help.
