My neighbor is a recent immigrant from Serbia. While he has a Master's in a medical profession, he also has a CDL and experience driving heavy trucks. He leveraged that into citizenship rather quickly.

He's on the road most of the time, working for a company, and gets great pay and benefits.

He's been encouraging me to get my CDL, as I've already had most of the training but currently drive such things using a CDL exemption, and team up with him now-and-then - apparently it's a great life for some, and the compensation he's dangling seem quite appealing. And his wife enjoys him being out of town most of the time, and is my go-to petsitter, so who knows, this could work out.
