Is the American visa signed by the whole family or separately by the whole family?

It is recommended that the family sign together, because it is better for the family to travel naturally and take care of the children, thinking that this can prevent the visa officer from suspecting that you are going to the United States to have a baby. The visa pass rate is relatively high. However, the United States belongs to a developed country and has a certain probability of refusal. Generally speaking, the pass rate is not very good. On average, the national average is only 40%. Whether the visa can be passed mainly depends on the following factors:

Have you ever been to a developed country like America?

Are you married with children or single and divorced?

What about the assets in your name?

Do you have a steady job?

Is the registered permanent residence in a sensitive area?

If your own information is better, followed by family members signing together, then the signing rate is definitely high.
