Question 29 on DS 156 asks to list previous visits to US but there is a small box albeit it scrolls.
Do you have to list all visits or just 4-5 should be ok? I have had over 18 visits.
Also do we have to list number of days for each visit too?
When I filled in my DS-156 for my K-1 visa, I had 70-80 visits to the US. People living in Canada often have such numbers. I simply wote details about my last visit to the US and then mentioned how many other (approximate) trips I had made to the US.
