I got Stamping on May 28th at Charleston, SC. Till now i did not received my GC... Is there any number that i can call to know the status of my Green Card... I am leaving to India in 3 weeks, i do not have any AP's(I gave to INS on May 28th at Charleston) BUT i do have the Stamping in my Passport... Is this SAFE or enough to travel to India and come back to US
