Hi Jeremai
Welcome. I recognise you from BE ( I'm a member there as well). Congrats on the baby, BTW. I havent posted much lately, lots going on. But we are going through he same thing. A letter should suffice as its mainly they just want to know you wont be dependant on the government, But anything more to help will be good. A letter of recommendation on your previous job, any bank statements or maybe equity in a home to be sold. Maybe even writing down any qualifications so to show you are job worthy. I'm the Brit and my husband is the USC in my case. Good luck. calle
