Visiting Boyfriend in England from USA

Surely it is very simple. I'm visiting my boy friend and am staying with his parents....

Yes it is simple, but the simplicity is that what you are advocating might raise a redder flag than a less detailed response might, in the unlikely event they are asked anything more searching than length of stay and areas they plan to visit.

#17, while you should not tell lies, you should still think about your answers to the typical questions. You could say 'I am going to visit my boyfriend' or you could say 'I am going to see the British Museum, Buckingham Palace, Tower of London, Big Ben, London Eye etc. (or whatever strikes your fancy)' and both can be true. But the former is more likely to mean additional questions while the later is more likely to satisfy them. Those who tell you always to tell the truth, the whole truth and nothing but the truth are misinformed. For example, the US wants an address in the US where they are staying from foreigners, what if you have not decided which hotel, what if you are getting a rental car and will just find a roadside motel, all perfectly reasonable but you will not get past US Immigration until you have given them an address, so look in a guidebook, pick out a hotel and give it to them, nobody cares if you actually stay there

Google is your friend: do you need a tutorial?

I think that is really unhelpful advice ... firstly, a couple of us who are not UK/Euro passport holders have already advised that the question-asking is mostly perfunctory, and secondly, to say she is just visiting for a month and tootling around on holiday is not a story that will unravel, since it is true. It is not necessary to gush your whole life story!

On the contrary, Fwoggie's response is the best advice on this thread. While she might well be waved through after minimal questioning, she might be screened in more detail (particularly if she has less money that the typical tourist staying for a month). If this happens, the sort of documentation that Fwoggie lists could make the difference between being allowed in, or being turned round.

Incidentally, this concerns possible issues with Immigration. Customs has nothing to do with any of this.

Here are 155 results to a topic-level search for "denied entry" within the UK&Ireland forum on LP. Since I'm not doing all the work for you, I leave you to browse through them to see if many of them bear similarity to OP's condition.

I asked a friend who does translation for the UK Border Agency, dealing with people who the immigration officers are considering to deny entry to (so only a tiny subset of visitors seeking entry to the UK). The advice that I got is that if the subject of your boyfriend comes up they will want to know how you met, how long you have been together and that sort of thing. If your relationship beforehand has been ONLY online that will be a big red flag but if you have spent time together in the US that will be a positive factor. Another bit of advice is if the subject of marriage comes up in the discussion, you should make it clear that is not your intention during your visit as it is not allowed under the standard visitors visa or exemption, you need a marriage visitors visa for that.

No I don't need a tutorial thank you, just a few stories from the Op who seems to be struggling to back up the claims.
Simple really - why, are you struggling with it too?

I didn't "back up the claims" simply because it is something easy to find on Google.
