Recently, several friends have entrusted immigration agencies to immigrate.

Of course, professional things should be done by professionals, not only in terms of fees (lawyers, notarization of information, travel expenses, tuition fees), but also in terms of how you get tuition fees. If you take over something you don't understand, you must understand it from many aspects, including the cost of doing something wrong, the time cost of learning and so on.

Many people think, I will do it myself first, and I can't find an intermediary. However, when you fail, your record will remain in the system of this country, and you can't help anyone.

Either change this country or stop doing it.
