Renamed after emigration.

1. Renaming has legal basis and convention. It usually needs to be published in the newspaper. Whether it's Zhang San before, Li Si after the name change, or the same person, the previous certificate is still valid, as long as the name change certificate is attached.

2。 Canada can have dual citizenship. I don't know why you want to give up your Canadian citizenship. Unless a new country is not allowed to have two nationalities, it will take some time for him to be naturalized even if he immigrates to a new country.

3。 Did he immigrate to a new country before or after you got married? If he is married, your information must be in the information he applied for, and you can move in with him. It doesn't matter if he is him or you are you before marriage.

4。 Suppose he changed his name before he got married, the immigrant took a new nationality and married you. You don't care what nationality he used to be.

5。 Suppose he got married, changed his name and immigrated. You are already his wife, and immigrants must fill in your information, so it doesn't matter whether you change your name or not.

6。 Suppose he got married, changed his name, emigrated and didn't write your message. (This is illegal) After he passed, he got his nationality. At this time, you have to ask his relatives to emigrate, and your previous marriage certificate proves that you are husband and wife, then he will be locked up in prison, and his new nationality will be invalid and deported.

7。 Suppose he got married, changed his name, immigrated, and went back to Canada to help you immigrate to Canada. He didn't write your information, but used his old name (which has violated the law). You immigrated to Canada successfully, but if you find out, it will be invalid. Because people with old names no longer exist.
