This is not an issue. You can get an electronic Visa in America. It is not that hard to do. All of the requirements are listed and it is not that difficult.
Being married won't help short term but immigrating to the US it will. I've done the entire process and unless it's long term it is impossible to get a tourist visa especially if married. The wait time is long and outcome is unpredictable. All the forms are online at USCIS.gov do it yourself no lawyer it doesn't help just costs way more.
I got my visa me type o married to a Thai in usa from e visa sight and it didn't seem to have an availability problem. That's just my experience from us not uk.
