My admit until date is on Jan 13, and I was supposed to leave on Jan 12. Unfortunately, I received my covid test today (Jan 9) and it came out positive, so there's no way they will allow me to board the plane. I immediately went to the USCIS website to file for an extension online but the website is down. So, if ever the website starts working again tomorrow and I am able to submit my application for b2 extension ONLINE, will that be alright? Like, how long does it take them to give an acknowledgement that they got my online application?
I understand that I should have done this 45 days before my stay ends but here we are. I'm hoping to be able to submit it before Jan 13. I will also try and give them a call tomorrow for clarification about this but I'm just really really worried right now if it would even make it on time if I submit it online.
