Visitor Visa - B2

First of all thanks to immihelp and all the contributors.

My parents applied for visa to visit my elder brother and his family staying in the USA.

OFC Scheduled 20 May 0100 pm
Interview scheduled 21 May 0900 am

Reached for OFC on 20th May at 1200pm. As my parents were about to enter the security guard asked for DS-160. I showed the same for my father which also had information about mother as she was traveling with him. The office out here told that every individual must fill DS 160 of his own and hence my mother was supposed to fill DS160 also. He also guided me to nearby cybercafe for doing the same. (Don't be panic at any point of time.) There is a cybercafe at about 10 steps from OFC location. As I entered, I found many applicants visiting this cafe as they had difference in their names on DS160 and Passport. So please make sure you have the name on DS 160 exactly same as that of passport.

In my case I filled out entire DS160 for mother and submitted it. While filling that there was a question

Who is paying for your trip?
In mothers DS 160 i wrote that my brother is paying but as I checked my fathers DS 160, it said Self. Again I had to correct my father's DS160 also. Since my brother was sponsoring both of them.

Finally I printed both DS160 and my parents entered OFC.

Next day was smoother

VO: Why do you want to go to the USA?
Father: To meet my son and tourism

VO: Where does he stay?
Father: ZZZcity in YYYY state

VO: How many days you plan to stay in the USA?
Father: 3 months

VO: Congratulations, your visa is approved.

Tips:

1. Fill your DS160 carefully as it is the document against which your answers in interview are evaluated.
2. Make sure the name in DS160 is exactly same as it is in passport.
3. Most important : every individual must fill a DS160

Thanks to immihelp again.
