Inviting widow pensioner mother for Master's degree Graduation Walk

[cr_p]

Hi,

I am a Master's student who will graduate in December 2016. I lost my father (who was a Govt. Employee) to cancer 4 years ago and my mother is receiving his Pension money which is pretty substantial.
My mother had also worked as Admin in schools before. She retired (Stopped working) 2 years back. She is 50 years old.
My mother has documents to show that she has one property shared with siblings.
She also has about Rs. 27 lakhs in her bank account in Fixed Deposits.


Questions:
1. She is visiting me for Grad walk, but will the VO see her as a person with low ties to India? How must we present the facts to demonstrate that she is in fact just visiting me?
2. There is no option to show pension money in DS 160 . Even "Other" option asks for present employer. Which will be misrepresentation of facts of entered. What is teh right way to show the pension money in order to prove the point that she is well financed at home?


Thanks,

1. May be. Do you have any siblings or grandparents? If yes, that will be good strong ties back to home country.
2. Occupation you have to select retired. You don't need to show pension income in ds-160 form. But she can show her pension documents to visa officer at the time of interview.

Thanks for your valuable suggestions, jnk.
But siblings and grandparents are just verbal explanations and mostly wont even come up during VO's conversation I suppose.
Is there any other precautions I could take to ensure the interview does not go untoward?
