US Immigration from Cuba

Hey there. I am planning to mail my application tomorrow 4/22/2020

I am hoping for some additional feedback before mailing my file off.

I am located about 1 hour north of Detroit my fiancee is Cuban. Will my application to to California or Vermont? I understand that the pandemic may work out as both a blessing (I have had time to finally complete our application and get it mailed out) and a curse delays in processing. Now that we are 30 days into Covid19 here in the US are we seeing decreased processing times?

We are front loading our application with affidavits from friends, plane tickets (4 trips in the last 12 months), his translated birth certificate, text messages, whats app call records, wedding announcement + receipt for my wedding dress (and a photo) and photos us us with family and friends in Cuba.

Should I be including anything else?

Should I separate my supporting documents by trip? as in:

trip 1 - boarding pass + air BnB + dining receipts + photos

trip 2 - boarding pass + air BnB + dining receipts + photos

trip 3 - boarding pass + air BnB + dining receipts + photos

trip 4 - boarding pass + air BnB + dining receipts + photos

Or should I group things by type: all boarding passes, all Air BnB, all photos

What order of supporting documents would be best?

Anything else I should be considering?

5/9/2020 we met in Cuba while I was on vacation

7/3/2020 I returned to Cuba, spent 2 weeks and we decided to get married

11/16 I returned to Cuba for another 2 weeks
