Hello,
Once your I-751 has been submitted and you have received the 48 extension letter, is it advisable to periodically check the status of your interview/card. Do you check on my.uscis.gov occasionally, or do you wait for them to contact you?
We are able to track our case through the IOE inscribed on the back of the check cashed. How concerned one be if we dont' recieve a text despite sending the G1145 form?
