It's not a mobster way, more like a weasel way. The reason it is a weasel's move is because decisions at the consulate are made by consular officers who are career public workers and won't deny visas for arbitrary reasons. That is bad for the political leadership because they just don't want to issue visas. So they need to invent evasive moves to throttle the pipeline by adding trainings, background checks, and other bogus bureaucratic hurdles.
