我是公民，六月份为我母亲申请了绿卡，她现在在美国，今年初B2入境，现在已经超过了六个月，也就是说签证已经过期了。
今天我们收到了一封信，看得不明白，请明白的的朋友们指教
-Obviously this immigration officer is very inexperience. Your mother and you may visit the local office to see what they say and then, file the I-485. Or just ignore this letter (not need visit local ofice) and then, file the I-485 and justify that your mother is your immedaiet relative and her unlawyer presence should not affect her I-485 filing and approval (this rule is in the I-485 Instructions and print that page out and enclose it). Enclose this I-130 approval notice with her I-485 filing.
