As someone who has gone thru an immigration process, for those curious about Jorge's finances, we had to show financial information, bank statements, bank account numbers, my pay check stubs for a certain length of time, several years previous tax returns, very in depth info.
Granted we weren't doing a K1 visa but I imagine the requirements are the same or similar. So I'm not sure how Jorge proved anything, unless they used bank acct info and previous year's tax returns. You have to be able to prove you can support yourself and the immigrant as well.
Then again, idk how Jorge could use bank acct info when most banks don't want marijuana dispensers using the bank for their income. Idk, it's beyond me how he proved anything.
