Can my relative wait in the United States while waiting to become a permanent resident?
No. Your relative’s approved petition gives your relative a place in line among those waiting to immigrate. It does not give permission for your relative to live or work in the United States while he or she is waiting to apply for permanent residence. If he or she enters or stays without legal status, it will affect his or her eligibility to become a permanent resident upon reaching his or her place in line for issuance of a visa.
