Hi. I realise the post below is somewhat detailed but this has been a source of considerable anxiety and I would be very appreciative if you took the time to read.

I am a male in my early 20s. Earlier this year my partner, who lives with me in the UK, got very ill and as a result it was decided that she best seek treatment in the US near her home and family. She is a US citizen.

I am a Bahraini citizen, in possession of a valid B1/B2 visa currently resident in the UK (but spending a very substantial amount of time in Bahrain). I am a student at a major British university, in my last year of my undergraduate course (and unofficially I hold a major role in our family business).

Since my partner left for the US, until she is well enough to return (probably January), I am planning on regularly travelling between Scotland and the US. I have already visited for 25 days recently, when the CPB officer just asked 'business or holiday?' to which I answered 'holiday' and was admitted. That was the entire conversation we had. I am slightly anxious given I am aware of the red flag that visiting your girlfriend can have- and I do not know if turning up at the same airport a month and a bit since my last visit would also be a red flag(?)

I have arranged with my university to facilitate a schedule that allows me to do this, and have a 23 day visit planned in October, which is what I am concerned about.

My plan for my time in the US is as follows: we will be spending 1 week at their vacation home in Maine, going horseriding, dining out, hiking, etcetera. We have a weekend planned in New York City, and we will also be visiting a friend of mine in Atlanta. The lion's share of the time will be spent, however, in my partner's family home (this is the address I plan to give CBP... bad idea?).

I can very easily obtain documents from my university that I am an enrolled student, I have just paid one year's rent upfront, and my father owns a major business in Bahrain... I have no reason to stay in the US, and if I ever wished to permanently move there I can legally obtain the correct documents without much hassle, and I would not dream of entering a country illegally or without obtaining the proper visa for the purposes of my visit first.

My only worry is what do I say to CPB if they ask more detailed questions, without putting myself at a disadvantage. I think it is very sad that I have to even consider all the above, given that I am just a man looking to do something perfectly legal, leave on time while spending a substantial amount of money in the US benefiting businesses, etcetera, but it is what it is.

For the record my passport is full of stamps and I hold valid visas for most major Western countries. Last time I felt a bit more comfortable as I was flying in paid F return, which I thought would hold up more if asked for a return ticket than my upcoming flight in Y.

I will not have a tremendous amount of cash on my person but do have multiple cards that can more than cover my expenses in the US.

Any advise would be deeply appreciated- this is making me a bit sleepless as I cannot afford to be disallowed entry into the US, and being put in such a situation would be disastrous!
