Once you get by this section it's fine . Like I said I almost applied for the wrong visa because of the glitches. I applied for a Non Immigrant O Visa it was simple I got my visa in 6 days. The only documents I had to supply were the passport page, Passport Photo, proof I'm in my country. I used my licence, and proof of finances. Good Luck
I found the first part of the E-Visa site where you put in what visa your after is glitchy. It almost happened to me, as it kept crashing and timing out.
