Yeah. I get questioned about the Somaliland stamp at the UK border every single time I re-enter the country, so I am not looking forward to the same thing by US officials. Early next year I'm also going to Sudan and possibly Yemen. I'm going to be on every government database going.
I'm still waiting for the trade mission to confirm my place on the US trip then I'll call the US embassy and see if they can advise. My strong preference is to travel on my current passport.
