I am an American citizen planning to visit the UK for two weeks' vacation. I am going to see my boyfriend who is a UK citizen and we thought it would be nice to visit Paris together.
I know I do not need to apply for a UK visa since I am not staying longer than six months. My plan is to go to the UK for a week, visit France for a weekend, then return to the UK for another week. From my understanding, American citizens are not required to have a visa to visit France if the stay in France is less than 90 days. I want to make sure re-entering is easy / possible before booking hotels and rides to France.
Will there be any problems re-entering the UK if I leave the UK to visit France for a weekend (2-3 days)?
