My passport application was wrong on my parents' date of birth. Does it affect the immigrant visa? How to change it? How long will it take to change it?

The form you fill out in the passport application form is used for domestic entry-exit inspection. In order to issue a passport, it is not audited by the immigration department. The key is whether your parents' date of birth is wrong on the form when you apply for immigration. If it is correct, it is good. If you make a mistake when applying for immigration, you'd better give an explanation to the immigration bureau.
