A very easy way to verify a remote candidate's identity is to buy them a plane ticket to an in person interview.

If they cannot board a plane using their claimed identity from their claimed city of origin, you can stop there.

Only if they are 100% fake as opposed to farming out work to someone else. I can turn up to an interview in person no problem. When hired I just have the person in India use my name/picture and do the work.

Of course if they hire me as opposed to that person in India directly there is likely a reason they wanted someone in the US. Often those reasons are legal and somewhere a law is being broken.

Easy, but expensive way.

Are you really going to do this for all candidates that make it to the final round of interview?

Are you also going to compensate the time for the candidate if he doesn't get selected?

Unless what you're proposing is more a formality, and that unless the person doesn't show up he's guaranteed to get the job.

By the time someone gets to the on-site interview, the job should be "theirs to lose." You wouldn't be spending the cost of an on-site trip for every candidate that shows some promise during the distance interviews--you'd do it for those very few you're ready to give offers to already, but just want to double check a few in-person soft-skills things (and now, want to double check that he is who he says he is).
