my girlfriend is philippino working in china. she claims she can get tourist visa to come to usa. she says her girlfriend did it. is this possible?

Tourist visas are given in the discretion of the American consulate. Your girlfriend situation does not appear to be promising for tourist visa, but she can try. She would have to convince the American consular officer that she has sufficient ties and bonds outside the United States that she will not stay along with sufficient monies to support herself without working during the period of visit.
