Does it matter if your mother's family moves to her husband's family to apply for immigration now?

You need to go to the website of the country where you want to immigrate to find the score sheet and the corresponding list of materials. These requirements will be detailed on the website. You can go through the formalities after you find out what the immigrant country needs. Generally speaking, you need to see whether the other country accepts immigration laws and regulations, whether it is investment immigration or skilled immigration, then take your ID card, property certificate and nationality certificate to the public security organ for certification, and finally wait for the national certification of immigration.

Every country has different immigration conditions. The common types of immigrants are investment immigrants, business immigrants (entrepreneurial immigrants) and skilled immigrants (including employer sponsorship).
