ewallets (
neteller/Skrill/ecoPayz) would not work if you have to use your US information like bank account, id and address. These do not offer service to US residents.
If you have local documents you can open a new ewallets account.
Bitcoin will work for the non regulated US sites like Betonline & ACR.
Bitcoin will not work for Stars, Party or 888.
Look for local prepaid visa cards. Shops, gas stations and sometimes Western Union have them for sale. They are the easiest method. A simple google search might find out where is the closest place to you to pick one up.
Stars, Party & 888 international versions are regulated. You will encounter problems verifying your accounts and withdrawing if you only have US documents. All 3 of these sites you must verify your account to withdraw. In the case of Stars they will ask you to send them the documentation within 14 days of opening an account. If you don't send it your account can be frozen and only be unlocked if verified.
