I-551 stamp or card
This confuses me. What is that? lol
I am just wondering about taxes. Also doctors/dentists etc always ask for it.
So once AOS is approved they can or can not get a SSN?
They are 10,10 and 12.
Documents that establish lawfully admitted for permanent residence (LAPR)
-- I-551 card
NOTE: Some LAPR aliens have conditional 2-year I-551s (Alien Registration Receipt Card), subject to the limitation that they must apply for removal of the conditional basis 90 days before the second anniversary of the admittance date to the United States. A conditional I-551 is identified by an expiration date 2 years later than the admittance/adjudication date is acceptable proof of permanent residency.
-- Temporary I-551
Temporary evidence of immigrant status is issued for an alien to use until the permanent I-551 card is received. This may be a stamp in the individual's passport or on the I-94.
