US Immigration from Uganda

Will all of the closures and what not going on, I wonder if the govt will decrease operations at the NVC due to caronavirus.

Had an interview, took all documents and they asked for more documents. We have to DHL the embassy the copies and then wait again. We are a responsible couple, and no reason for delay. I just don't get the long long process, over 90 days now. We have medical insurance and a job waiting.

I am curious how often married people are denied at the interview?

Probably the one area I'm most concerned about it just the time we've spent together. My wife lives in Uganda and so travel over there is really expensive and it's difficult to go over more than 2 times per year. We've been married 10 months and knew each other for about a year before we got married. We talk 2-3 times a day every day on WhatsApp and we also have leased a small house over in Uganda together, so we'll have the lease with both of our names on it. I pay 100% of her living expenses and have done so for quite some time. This year, we are going to file US Taxes together for 2019, so I'm sure that will help.

I'm sure it is probably difficult to have an exact answer to this question, but just wondering.

Thanks

Is the DS-5540 required for CR1/IR1 interviews? I am not seeing this doc listed in the different procedural docs and howtos for the interview phase of the VISA process.

I am working on filling out the I-864 and had a question about section 2 for the principal immigrant. My wife lives in Uganda and they don't receive mail directly to their houses there like we do here in the US. What address should I put in the "
Mailing Address" section since daily mail service isn't general a service Ugandans have.

Thanks
