回複：Can I file second I485 even if first I485 is in pending?

OF COURSE YOU CAN. JUST MARK IT IN FORM I-485 TO INDICATE WHEN AND WEHRE YOU HAVE APPLIED BEFORE. ON PAGE 2 IN THE MIDDLE THERE IS A QUESTION ASKING YOU IF YOU EVER APPLIED GREEN CARD BEFORE. YOU SAY YES AND TELL WHERE AND WHEN AND RESULT "PENDING". PUT YOUR FIRST I-485 RECEIPT NUMBER THERE SO CIS CAN CLOG BOTH TOGETHER.
