1. go to https://infopass.uscis.gov/info_en.php,然后make your appointment with infopass
2. type in zip code
3. 然后选择“You need Service on a case that has already been filed ”
4.然后选择“Case Services follow-up appointment ”
但是我这里就有点不太明白了。首先必须是要打电话45天之后才能去infopass吗?是不是这45天中,移民局会寄给我个所谓的service request ID?
因为网上感觉infopass想预约就预约,没看见poster有提过都是等45天之后才去的infopass
