I know it is possible to come over every year because Florida is full of UK and German residents who do it. I don't know whether they get the 10-year multiple entry visa, use the visa waiver program, or apply every year. It's sort of odd to give someone grief over using a program that was designed to cut US visa processing costs.

Sometimes people get in trouble with dates, because they count the day they leave one country as the first day out of the country rather than the last day in the country, then try to come back too soon. I actually got caught by this in SE Asia. I needed to be out of the country for 90 days, and thought that when my 90 day visa in the next country was up, I could return. Wrong. By their count, I had only been away 88 full days.

Take Bev's advice, and check it all out very carefullly.
