After Visit some "Immigration" Lawyer, who do not show any interest neither care about my case, just made me loss my time and money, 15 days before interview I went to his Office, and they where very well organized, they really care about your case, they worry about each weakness of your case and fix it, they trained me for the immigration interview, he not only was in my interview but fought until last minute and you know what, my passport was sealed by the immigation officer. and my GC is on its way. I recomend highly this lawyer and his team.
