Drug dealing and prostitution work pretty well lol jk jk :P
Go to some Mexican restaurant, I bet 100% of them have undocumented people working for them. Getting a job is not hard, go to any restaurant and ask for an application, but don't expect to become a waiter, if they offer you a dishwasher job take it.
