He has a SS number. He had H1B years back before he switched to my moms AOS case as a beneficiary. The case went haywire for several years so all the beneficiaries (my siblings, dad and I) lost status but a judge eventually granted my mom (and her only) a green card recently. As far as his verification of status goes, I can’t tell you how the health care rep fills out the application as I haven’t seen it myself. He had pre existing conditions so he can’t be without insurance. I think we will just stick to Obamacare for my parents for now and pay the premiums.
