I can't seem to find clear answers for this. My daughter is studying at U Penn for 6 months and has to go to London to have an interview for a visa, fair enough. I am going with her for a few days to settle her in. Do I need a visa? I have an electronic chip passport valid for more than 6 months and a return ticket. Do I need ESTA(????). We went to the caribbean last year and just needed to fill in immigration forms on the plane, same as New York, but that was 7 years ago.
Would hate to get there and not be allowed in!
