Simply put, how willing are ladies in the US to accept provider references from their foreign counterparts?

For example. Say John Doe travels to Canada for work. Seeing a provider there is legal so he indulges himself. The provider gives him permission to use her as a reference. Now he wants to see a girl in the states. Is  this previous reference still good? Or is this clearly a case by case, different providers will have different rules kind of thing

Escorting is legal in many parts of the world, so a gal seeing a guy LEGALLY, does me no good except to tell me he did not rip her off or beat her. It does not mean he can't come to the U.S. and work for the cops, or choose to become one. Now, if you saw her in an area that it was still illegal, maybe so, but I would probably pass. Most women who work in places that are legal have no reason to screen, meaning she knows NOTHING about you. I require more than refs to see someone for the first time.

This is interesting... I'm about to find out soon if I'll pass the screening or not.

I'm usually in Europe or Asia so I know very few ladies that might be suitable as references.

I do have a date-check account. Though, with only one lady on it.
