US Immigration from Sri Lanka

Quick question guys, we have cheap flights from Sri Lanka to Washington Dulles international airport but the problem is that the transit will be from Uk. Will I have to quarantine as I will be coming through UK? How do I find any information on that?

Hi guys! Have a good day! What should you do if the petitioner change the address after the interview is being scheduled? As the previous address is mentioned on the DS 260 and I 864, will that be an issue? Petitioner also got a new job offer (previously wasn t making enough to sponsor, so we used a joint sponsor) which hits over the125% as advised on poverty guidelines. We are planning on taking a new i 864 to the interview with proper evidence of the new employment and show it to the consular officer, is that okay? And we also want USCIS to send the GC to the old address as that s the only place we can trust. I don t know what should I do. Any thoughts?

I just received a RFE saying that I need to submit Supplement J along with I-485. However, the instructions says it is not needed for EB2-NIW applicants. I even specified this on my application. What should I do?
