What's the difference between professional immigration and overseas labor service?

Few overseas labor service companies can use professional immigrants. Do you mind talking about immigrants from any country? Generally immigrants use money, only when they have fixed assets or real estate. Professional migration is a very special type of work, and second, domestic companies have head offices abroad (this situation is rare, and foreign countries recognize that you have a lot of money and rarely do it), so generally speaking, most of them are deceptive.
