A Great Representative

“Mr. Barbosa was a great lawyer. He was very easy to understand and made us feel like we were his number one priority. Very knowledgeable and trustworthy in a field full of money hungry lawyers capitalizing on immigrants who are sometimes lead to believe there’s a chance when there’s really not.

LGBT marriage petition approved! Great Service!!

After the June 26, 2014 supreme court decision overturning DOMA, my wife and I decided that we wanted to be formally married. To give a bit of background, she was already in the country legally for a year on an F1 visa. After the supreme court decision, we wanted to submit the I-130, I-485 Adjustment of Status and the I-765 Employment Authorization. To say that everything required by USCIS is overwhelming is an understatement. We turned to Mr. Barbosa to help guide us through the process and ensure that we left no stone unturned. He was AMAZING from start to finish. He always made sure to be available when we needed him or had questions. He went above and beyond to make sure our case was being handled appropriately. Since we didn’t know much about the process, we really had to trust him with our case. Luckily, he didn’t let us down. He really takes the time to know the details of his clients and design a custom strategy for whatever your needs are. After the horrible experiences we had with previous attorneys, Mr. Barbosa was a god-send. I will never turn to anyone else ever again. He is definitely our attorney from now on. We did exactly what he told us to do, we trusted whatever he did on our behalf and during the final marriage interview, it was exactly as he had predicted. We were approved immediately at the end of the interview! This was not luck. It was because he had us completely prepared. Since he had prepared everything so meticulously and since he prepped us on the process so clearly, everything went super smoothly at the interview. And last but not least, he was priced VERY fairly, as compared to other quotes we received from other attorneys. If you want a person who actually CARES and really does keep his word, I would highly recommend Mr. Barbosa. A+ all the way!
