<human>: I'm looking to apply for a tourist visa to the states in advance because I want to be ready in case I see insanely cheap flight tickets there and I might make a very last minute trip there without worrying about "how long is it going to take to get my visa, is my visa going to be approved or will I be wasting my money". I know people from my country who managed to apply for business/tourist visa and the visa is valid for 10 years, so I thought it shouldn't be a big problem if I don't have exact itinerary yet.

I tried applying for B2 visa online and was asked to input estimated date of arrival (this I have no problem making something up). And then I was told to input contact details of a person or organization from U.S who can prove my identity or sth like that. The problem is I don't know people who can help with with that, and since I have not been in contact with organizations (tour agency or hotel) I can't find something to write in the fields. Any idea how I can get passed this?

Some background about myself:
- I'm from First World country (so I think) and we have visa-free to 150 over countries, all except U.S for some reasons. But generally people of my passport are not known for overstaying or illegal immigrants etc.

- I have no problem proving strong ties to my current city, no problem showing work contract and salary slips etc

- I'm single Female

- no criminal records, good credit records, good citizens, good travellers (didn't overstay in any country at all)

Give me a shortened version of the text
