I'm pretty much aware of futa tax it's because I was one of the beneficiary some time back. Unemployment benefit is just it's matter not immigration, this is your wrong assumption ,federal benefit is an immigration matter as if Feb 2020 n it's now reported on u our immigration file .we have to declare it while in change of status if u have seen firm after 2020 Feb. It's not that my wife is not qualified for benefit from IRS ,it's just that it's reported to immigration . Anyways I decided to go this way until she is secure .for best consult our respective attorney for best answer and move accordingly.
