首先想從心底對8老師您說聲謝謝，從年初我遞交485開始，到後來我丈夫突然在中國病故，我需要申請加急AP,8老師一直再幫助我。沒有言語能表達我的感激之情！
我的工卡明年2月15日到期，我準備申請renew,有兩個問題想請教：
1。可以onling renew嗎？
-Yes. After e-filing, you still need to mail the support documents such as photos,I-485 receipt, etc. to USCIS address indicated in the e-filed verification letter/notice (print it out after you complete the efiling and enclose this letter with your support documents).
By the way, you need to pay the filing fee if you use e-filing. So, you may just use paper-filing without fee.

2。需要寄照片嗎？
-Yes. Same requirements as you did first time.
3。從寄申請開始算起，大概多長時間可以收到renew的工卡？
-Normally about 3 months, case by case
