US immigration question

[Neoshoegal]

We're off to the Orlando at the end of the week to go to a convention for work. We won't be doing any work there, it's just to learn. We'll also be spending 2 days at Universal for fun.
They always ask you at immigration whether you're visiting for business or leisure. What do I answer this time? I'm there to learn for my business but not to do business. Also, I'm a bit worried about all the questions we might get if we say we're there for business.

Just say what you have just said, just attending a convention for a few days then having a few days holiday before returning.

Your primary reason for the travel is business, tick the yes option on the custom form and say so if asked.

There is no reason for you not to say otherwise, they will probably ask the nature of the business, simply tell them.

I've never had any more difficulty going in under a business trip reason rather than a leisure trip. :thumbsup2

On our holiday in Aug 2006 I ticked the leisure box on the form and when we went through immigration they asked me what my occupation was.:confused3
