Hey, i was thinking about visiting an friend from USA 2 weeks living at him i would not spend any money on rent or so only food etc, i would have around 600 dollar to spend. I live in Europe, and i have an esta visa passport creditcard yeah everything i need for the trip. Ofcourse i would buy a returnticket immediatly when i book so it is very clear when i go to US and when i go home again, my question is i think it is very blurry.. how much money do i need is what i have ok? this person that invites me to live with him could also confirm his invitation in writing with all his information adress name workplace etc, my question is more, should my situation be ok?

This was the information i've found about money: "Travelers visiting the U.S. from a foreign country must be able to prove to a CBP Officer that they have sufficient funds" and then "CBP Officers are aware that there may be circumstances in which a traveler may have limited funds. In those cases they will determine the admissibility of the traveler based on the information provided to support the reason the traveler has insufficient funds." and about me living with"

And this was the information about visiting: "If you have invited someone to visit you with the understanding that you will be hosting them at your house and providing meals, etc., it is advised that you confirm your invitation in writing so that they have something to show the CBP Officer. The letter should include your full name and address. This will not guarantee their admission into the U.S., but it will help the CBP Officer fully assess their situation."
