There is a small 401(k) Plan for a company where several employees provided false SSN in order to collect paychecks, etc. The company did not verify and as some time had passed, the employees that provided false SSN were able to get into the Plan. The company made contributions on their behalf. The Plan itself deems "non-resident aliens" are ineligible from entering the Plan. It was found out that said employees were in fact not of legal status to be in the United States.
(Still receiving further details.)
Would the employees just receive their contributions to the Plan, their contributions with the employer's contribution, and what would they be entitled to? I am seeing some cases where employees that fraudulently self-identified because of immigration/legal status had to go through Civil Claims.
