Can American immigrants have immediate family members who can make an appointment for many years and then go for free when they wait?

You think too much ~ ~ children's shoes ~ ~ ~

Even if your relatives were born in the United States, it is impossible to make an appointment as you said and go for free.

For immediate family members, it usually takes about 10 years to apply for immigration, which means that if you apply this year, the embassy will interview you around 2022, or longer. The related expenses of immigration still have to be paid. You can only get a visa if you have a face-to-face visa
