B2 visa rejection for parents, help needed

[mintuambala]

Hi All,

I am on H4. My parents appeared for b1/b2 tourist visa interview in Jan this year. Unfortunately, their visa got rejected. Just to let you know they appeared for interview in their NATIVE language.

INTERVIEW process-

The VO asked them 3-4 questions about my husband (his company name, position, place of residence etc). They provided correct information to all the questions.
The VO took their passports and went in the back office for a minute and then came back and asked my parents to go to other window where a lady would help them. The lady asked my father about his siblings and their names and then asked if they changed their address recently. My parents said no and mentioned that they are living at same place from last 10 years. But they did not realize that they need to show the affidavit for address proof that they got notarized, as mom's address is written differently on passport and does not match completely with the address on dad's passport. She then asked them to leave and said that information will be updated online (which means their visa was rejected).

QUESTIONS-

1) Seeing the scenario and questions that they asked, could the difference in address on both parents passport (they got their new passports last year) be a reason for rejection?

2) Its been almost 3 months since their last rejection, can I schedule their second visa interview? ( as my graduation is in june) Will it be safe?

3) It appears that VO once decided to give them visa, went to the back office after asking questions some questions and then came back (Not sure though) Any comments on this??.

I would really appreciate your guidance.

Thanks

why is there a difference in the address ? how much is the difference? why did they not get it corrected when they got their passports?

The address on my father's passport is complete. They both applied on different dates and somehow the address on my mother's passport does not contain complete information. They never noticed this difference. However, they got an affidavit notarized from court that the address written on their passports points to same physical location.
Here is the format of address on their passports-

Father's passport-
HNo 123B.II, Street name, Nearest road name, city, state, country

Mother's passport-
H No 123B, Street name, city, state, country

The fields marked in bold are missing in mother's passport.

Could this be a reason for rejection?
Thanks
