2 adults, one qualifies, second doesn't have SSN

[Ali BenAyed]

There's a couple that is interested to rent my SFH, the lady pre-qualified with her income, references, never evicted and clean criminal record. But her boyfriend has no Social Security Number to check his criminal record. Should I approve or decline them for not able to check the 2nd adult criminal background?

Also where is the income coming from? They would need something to get paid so if it is not an ssn it is a TIN. Something to prove valid presence in the US indicating they were screened for entry or use name and DOB.
