Visa rejection for my mother 2nd time: Mumbai Consulate

[kavora]

My mother is aged 49 years and is a widow. She has been rejected for the visitor visa U/S 214 [b] TWICE.
Our situation: I am working in US on H1 visa and my brother just completed his studies. I have one sister who resides in India. We wanted her to come to US to attend his graduation and spend some time with me and my husband.

She was asked the following questions 1st time:

1) why do you want to go to USA
Reply: Attend son's graduation, Tourism, visit daughter and son-in-law

2) how long do you want to go
Reply: 6 months

She was asked the following questions 2nd time:

1) why do you want to go to USA
Reply: Attend son's graduation, Tourism, visit daughter and son-in-law

2) what does your huband do:
Reply: He passed away in 2000

This time she was a little aggressive meaning she tried to show the Affidavit documents which listed her property, savings etc. and also her picture with her mother-in-law as she has been taking care of her old mother-in-law and hence needs to go back to India but the officer wasnt ready to see anything just asked her to leave.

My question:

Is it worth to try and apply the 3rd time with the same case details i.e. same reason for travel etc. Looks like most likely her visa would be reject the next time too - any thoughts?
Any suggestions for what we can do different would truly be appreciated.

there is no absolute answer or no one can say things for sure, however I would say i you realy need her here Try again.
There are many cases where people got the visa after 4 or 4th attempt.
Search in this forum for similar thread and Experience section and you will find some useful iformation.

I was thinking that My sister, who is the only child in India would also take an appointment for the interview this time along with my mother. My sister speaks English but my mother does not.(My mother is not very good at communication even with a Gujrati translator). Can they both take an appointment for English interview and my sister would do all the answering. Is that allowed?
Do you think that my sister going would help or hurt my mother getting the visas?
