How do I screen International Students???

[James M Smith]

I just had a group of international students ask to apply for one of my properties.  It would be 3 of them and 1 US citizen who is employed.  How the heck do I review their applications?  They claim they get $1500 per month in living expenses but I dont know what kind of documentation to ask for, other than bank statements, or how to determine if its legit.  Any assistance from someone who has had experience with such matters would be greatly apprecaited!  I would hate to have them pay $160 in application fees to just have me not be comfortable with the situation and back out.  Thanks as always to such an awesome community!
