Hi Mom,
So I changed my address and got a call from Tier 2 and she changed it on her end too. She told me that it is necessary to get the bio appointment this way. Now, I still have 2 weeks left of my current lease (3 weeks till the new tenet show up and change the name on the mail box to her name). Since, I have an informed delivery set up on my previous address till next 3 weeks, I still haven't changed my address in my USPS account to the current address just in case if IL/Bio letters go to my old address. Do you think I should change the address on my USPS account as well? Sorry it might be an annoying question but all I am thinking these days is that my letters could go to the new address and USPS might see on their portal that this address is not listed under my name and send back the mail to USCIS. The new mailing box is different than my old place though and it's not a USPS mail box with our names inside it (Just a typical mailbox for a townhouse).
P.S. My experience of speaking to Tier 2 agent: First she called and told me my case is pending and I should give it time and there's nothing she could do to expedite my case. Although I explained to her that my case is time sensitive and is under DV category, but she was still indicating that nothing can be done and I need to relax (She was a kind agent and carefully listening to me). I said thank you and hung up and after about 15 minutes I received another call from her. She said that she spoke with her supervisor and since you have the deadline of September 30th, I'm going to put a service request on your behalf and inform ASC and FO about your concern. In overall, she was caring and tried her best to help me with my case!
