催了USCIS,今天被告知
U.S. Citizenship and Immigration Services (USCIS) records show your case is
in line to be reviewed by an officer. We ask that you allow additional time
for this process to take place since we process these cases in the order
received. If after 60 days you have not received anything in the mail,
please contact the National Customer Service Center (NCSC) at the number
provided below.
