I was able to succesfully visit all the time without any special inquiry or questions. Last time i visited I stayed for 3 months and 12 days. I was given 6 months entry all the time I visited USA.
I want to know how long should I wait for my next visit to Boston?
Since my parents are citizen I do not have any I-130 pending and never filed any I-130.
I would like youe suggestion because I was planning to visit again in August for 2 weeks.

it is interesting to see you made so many back to back visits in 2013 alone without any issues.
There is no set interval laid down by law between two visits and it is entirely at the officer's discretion .

Still, in general, having spent 3 months recently and so many visits in 2013, you should take precaution and not enter
US for another 4-5 months for a pleasure visit.
An emergency or a business visit can be an exception.

I actually travel on visitor visa.
Since my family has a business there, is it possible that after adding my name to the business, I can travel USA on business visa more often for shorter periods?
What is the process of converting visit visa to Business visa or it is same for both but you just mention to them that you are going for business purpose.

you are not allowed to manage your business in US on this visa you have ( B1/B2). If you will add your name to the business, and travel very frequently then
they can stop you in suspicion that you are working.

On B1/B2 the only business you can do is meetings or dealings.

If you have business outside US, then you can look at L1 visa by opening business in US as well. But that requires one year of wait and several conditions.
Also, if you have green card options go for that instead of a visitor visa to manage your business in US.
