For the W-7. I think IRS wants her passport mailed to them which I don't want to do because mail in her country is awful and quite a few things get lost.

My wife and I got married earlier this year. She is not a US citizen and is living in Sri Lanka. I want to add her to my 401K plan as a beneficiary. When I try to do that, it requires a SSN or TIN. Is there any other way to do this? Can I write a will instead that leaves everything to her?
