All, 

I have a tax question and would like to ask for your input. 

I have a new client, which just turned 18. He is a U.S. citizen and has a SSN, but lives in a different country. 

His parents have no ties to the US other then being on a H-visa when the client was born in the US 18 years ago. They since have returned to their home country, do not have a SSN or a residency permit in the US anymore. They did not file US taxes for the last 15ish years. 

I am wondering if my client would be able to claim the Recovery Rebate Payments. If I start a return for him it asks if he could be claimed as a dependent of another taxpayer. Since both his parents are nonresident aliens, can I assume that he cannot be claimed as a dependent of another taxpayer? And therefore can claim his own RRC 1-3 when filing a tax return for 2020 and 2021? I cannot find any guidance for this scenario. 

Thank you for your input.
