2 1 the application time for unmarried children to immigrate to the United States

Your father can apply for you as long as he has enough tax returns for three years. There is no schedule (= unlimited places, still have to wait). In theory, within two years, most of them are one year.

If the legal guardian of your parents' divorce is not your father, you need a judicial letter from your biological mother agreeing to emigrate or wait until you reach adulthood (18 or 2 1 I don't know, I suggest writing to the consulate in the name of your father).

It doesn't matter if your father is not in the United States, but you must have an American tax return, if not. From now on, go to the newspaper, or pay taxes (very expensive).

If the tax is not done well, don't waste money to apply.
