"I am a university student residing in a country other than my country of origin. A few years ago I applied for a student visa which was denied and my tourist visa was revoked. Fortunately, I was able to get the services of Dr. Roa who, based on her extensive knowledge of American immigration laws, in a very professional manner and attending to my interests at all times, started a process with the American Embassy where in an extremely short period of time she managed to get me a new appointment. Thanks to the incredible work, knowledge, management and guidance by Dr. Roa, I was granted my tourist visa again and I am sure that without her total dedication to my case this would not have been possible."
