How does a husband get a green card in the United States and let his wife immigrate there?

Your supplementary question is almost impossible for those who have answered your question before.

As far as I know, if you have a green card, your husband should apply in the United States, and then the lawyer will tell him what to do. He pays the lawyer, who will tell him everything he should do and what his wife needs to do.

Usually, what I know is that when everything is done there, letters or documents will be sent to you, and then you will take these documents to the embassy for processing.

Also, the attitude of the embassy is very bad, which is well known. You must never refute what they say, and you must never show your opposition to their ideas, otherwise you will never want to go to America.

There must be a lot of documents sent to you by your husband when you go to the embassy, otherwise you will go to the embassy for nothing. I don't know why they called you.

The only way is for your husband to ask a lawyer, who will know everything.
