To travel into USA you have to register and to get a authorization before travelling.
For citizens of land which takes part in the Visa Waiver Program it is quite easy with the ESTA-Scheme. The registration, paying of fee and the authorisation is done online. Each applicant is asked about some personal information, eventual communicable diseases or if he/she have ever been arrestet or convicted for any crime.
The fee is about 14 Dollars
The procedure was quite simple and done within some minutes.
So we may travel to USA – if not somebody at the border guess we shouldn’t. 😉
