Really. US immigration is more perverse and frustrating than you can imagine. You might be fine, but just because someone said 'I did this and it was OK' doesn't mean it will be. If you aren't sure, take legal advice.
Also, point of information, ESTA isn't a visa. They did it on the Visa Waiver Program (VWP). ESTA is part of the process of entering on the Visa Waiver Program
