No mate but I dfo like to plan if things go well. We chat on the phone most days and on the net of course it is just that actually meeting in person so my first visit is only for a couple of weeks just to make sure she is as cool as she is in her videos ( clean ones )
Only if you're stupid enough to actually tell them (EG tick the box that says yes).
How else they gonna find out? I know someone arrested once (minor charge got a caution so there is a definate record of it.) goes to the states 4 - 5 times a year (buys clothes apparently cheaper to buy them there even with the air fare) never a problem. They will only care if they think you are going to cause them a problem or they think you maybe intending not to leave. (EG I have a girlfriend here why i'll just run be an illegal etc.)
Now if you want an experience go with Air India to New York, greeted by the feds snapping on their rubber gloves for the dozen or so fellow fliers whose names were read out just after we landed.
