父母移民登陸美國後半年了還沒有收到綠卡。臨時綠卡stamp快過期了。到綠卡申請的賬戶裏麵查了，也沒有什麽信息可用。因為綠卡申請已經批準了。該怎麽辦呢？謝謝您！
-Did you pay the immigrant fee for your parents yet? If no, you need to pay the fee, otherwise USCIS will never issue the plastic card to them. The immigrant fee is for the costs for USCIS to process and produce the plastic green card. If you have paid it, your parents should receive the plastic green card within 90 days. You may contact USCIS.
See this link for the immigrant fee:
