Visitor Visa

Hi All,

I have few queries regarding the Visa:

  1. Do you think it is a good Idea if mom, Sister, brother in law and my nephew appearing for Visitor Visa altogether?

  2. My mom, Sister, brother in law are working. As an tentative date I mentioned that all are planning to come on August 1st 2015 but that is not a vacation time so they have to take off. Is it risky or should I mention that they are coming in December during winter holidays?

  3. Specify the purpose of trip should be Tourism/Medical treatment (b2). Please confirm?

Thanks,

Megha

Can someone please help me here?
