American individual tourist visa

You have study abroad experience, plus your wife is pregnant, has a house and a car, and has a tax record of her own restaurant. It shouldn't be difficult, and deposit records are unnecessary. It is recommended to bring the real estate license and the business license of the restaurant. To prove that the restaurant is your certificate, your wife's pregnancy certificate and your wife's passport (if any, in order to prove that she has no intention of going to the United States).
