I was browsing the internet in search of Family Law attorneys and after a tough search, I ended up calling Mr. Chand (referred by someone) on a weekend. He was very humble and patient in listening to what all I said and carefully answered every question I had. Even knowing that I was out of state, he didn't hung up the conversation and it lasted for 15 minutes.
I really appreciate his knowledge even though his field of practice is different. His Ideas and Suggestions on Family Law really helped me and gave me an exact way to begin my case with.
There are tons of law firms who charge a fee and

Chand Parvathaneni is an excellent Attorney.He will answer your questions and will provide you all help needed..He is best in DFW to deal with GC,HIB cases and answering RFE’s. My case was very difficult and other lawyers couldn’t handle it. Chand helped me get my Green card case approved. I have been their client for more than 5 years now. They charge reasonable fees. I highly recommended him for any immigration issues.

I interviewed with some other firms in the area and found that Mr. Chand was very friendly and personable. As my case progressed I realized I made the best choice going with him, he was always very responsive and was even prepared for potential courses of actions beforehand. I can tell he really cares for his clients! H1B processing for my application was pretty quick.
