My receipt of notification for my address has been expired for awhile now and I haven’t had any issues. One young volunteer told me I couldn’t get another covid extension unless I update it, but I told him they’d never said anything before. So he let me go through anyway. That was months ago. The immigration officers have never said anything (including today). I’m still living in the same room listed on the paper. Do I need to get a new one and what is the process for that?
