IF you are flying into the USA, you have to have filled in an ESTA form, With out it you will not get in!!  
It is a form that takes the place of the visa waiver, the green form that you used to have to fill in on the plane before you get to customs.

I learnt about it here //http://forums.moneysavingexpert.com/showthread.html?t=846763but my travel agent also contacted me to check that we had it.
 
Apparently some agency web sites are trying to charge for this, DO NOT PAY, it is free!
This link is the official usa Govt wbsite, where you apply online   //https://esta.cbp.dhs.gov/esta

Thankyou so much Twistina,

That would have been rubbish going all that way to be turned away and sent back! Are you going? Be good to see you...

BEcky

Twistopher and I are now in Hawaii, Kauai island to be precise. ( Warm and Sunny!! HA HA! 8-)  8-) ) Just to let you know, we still had to fill in the green visa waiver form that I thought the Esta form was taking the place of, in order to enter the USA. It has exactly the same information on it so I am not sure quite what the point of the Esta is!!   :roll:  :roll:  :roll:  
Any way we got in, so see all of you who are going you all soon!
