How many ways to immigrate?

Immigrants include investment immigrants, skilled immigrants and passport immigrants. Investment immigration is to meet the provisions of the immigration law and apply for immigration by investing a certain amount of investment in the local venture capital. Skilled immigrants apply for immigration by matching their skills with local employers to obtain green cards in one step or matching employers' past jobs in the form of employer guarantees and meeting the requirements of immigration law. Passport immigrants are generally more in European countries. By buying a property, the whole family emigrated for three generations.
