What kind of background checks does uscis conduct when processing a I-30 Petition?

Question

For example mvd, bank, etc?

Answer 1

All documents that are submitted are verified if suspicious.

Answer 2

Police records, to be sure, for the petitioner and the beneficiary. They also check Immigration records, to see if there are any ineligibilities that need to be dealt with. Otherwise, most other things are done on a case to case basis, depending on what might be considered problematic.
