I am a 29 yo living in UK, on a South African passport (no visa waiver allowance with US), and I'm travelling to South America for a few weeks in July, with flights via the US and a stopover of less than 12 hours. The two US stopovers are anout 3 weeks apart. Unfortunately this means I need to get a visa - it appears that the C1 (transit visa) costs the same as the B1/B2 tourist visa ($160 for my several hours!!), and additionally seems to require much the same extensive supporting documentation.
I'd like to travel to the US again, so it seems way more worth the hassle and money to apply for a B1/B2, which may allow me to travel to US on holiday again without repeating the stress of the whole application.
So my question is - is it possible to be travelling in transit, but apply for a B1/B2 visa, while motivating intended future travel?
