US Immigration from Philippines

We're moving in a few days and filed Removal of Conditions just last month. When I tried to file the AR-11 Change of Address form using my USCIS account, I get the following error message: "You cannot edit your mailing address or physical address during this part of the adjudication process."

Below is the screenshot from the USCIS portal:

Should I proceed with AR-11 at all? Or should my USC husband just file the I-865, Sponsor's Notice of Change of Address?

I'm curious why USCIS cannot handle a simple address change for a freshly filed ROC.

Im looking for an airfare ticket for my fiancee. these is her route. From manila - taipei- sfo- seattle. final destination is seattle.

my question is: does san francisco custom get her visa check or at seattle?

We received our NOA2 back on June 14th and are still waiting to hear from the NVC. In the meantime we are trying to work on other documentation we will need. On the K-1 guide here, it says "Send an original letter affirming your desire to marry your fiance and your continued support of the K-1 Visa. Sign and date the form. This will be similar to the letter you provided with the I-129F, but dated much closer to the interview"

By "original letter" does it mean something I have to send via physical mail? I have written such a letter, signed/dated it, scanned it, and uploaded it to a Google Doc folder that contains our visa documents. Could she just print that out and take it? I have tried to mail her things before but it just gets returned to sender because I guess our postal service is useless at shipping things abroad.

Hello, It looks like the Philippines is no longer requiring Covid-19 Tests or vaccines to travel there! Also on a couple of Airlines Philippine Air and Korean Air are no longer requiring the Antigen tests to travel there according to their websites.

Hello, My Wife and step-son's DS-260's are DQ'd as of 7/3/2023, how long should it take to hear anything else from NVC or Manila about when we're able to schedule the medical's and interviews?

Thanks
