@pyackman what do you mean by consequences? what are consequences when filing a green card? some say there was no problem in the same situation. Please share your experiences and knowledge.

And also, if a person works in cash, that might not be a good idea, in terms of saving/depositing a lot of cash or personal check (how much are we allowed to save/deposit?), I guess, only bank has access to the account not the government? Paying off loans using that cash from the bank? Will there be records while filing a green card? so on

There are so many things people don't know about rules, loop holes and so on, people should know. This pandemic has taken a toll on people.
