回複：請教pjiang老師，8老師，綠卡的卡號問題

剛剛收到綠卡。在卡的背後有一欄寫著CARD# SRC07xxx（也就是I485 receipt no）。但是在寄來的紙上又寫著Receipt# SRC07xxx；CARD# 2B0511xxx。

1.請問這正常嗎？

-Fine.

2.究竟哪個才是卡號？SRC07xxx or 2B0511xxx

-The one in your GC. The card# you mentioned is just for the physical card (permanent resident proof) produced at this time. Whne you renew it, you will get another number. Actually, your green card number is your A# (also called USCIS number, Alien#, Alien registration#) which will never change for your life time.
