This question already has an answer here:
I'm from the UK and I've been to the USA once before. I want to go and spend the Christmas holidays with my girlfriend who is American. I am using the VWP which I have been approved for, but I am worried about my entry interview.
I have heard that CBP can reject people if they think that they plan to move to the USA, and that this is more common if you are visiting a partner.
How do I help the CBP agents see that I am planning on leaving within my visa stay? I will be providing return flight info and proof of income, is that enough?
Should my girlfriend come through immigration with me or should we go separately?
