Hi
Sanjam, 

Crimes that involves "moral turpitude"
do  have immigration consequence such as defraud, robbery, kidnapping etc  while other not. Do TABC fall under this category?I do not have any idea regarding this.

I suggest you to ask a
lawyer so that you can have "genuine advice" rather than having
"thought". You can post your question at http://www.avvo.com/.
I think it is free but I am not sure. If not you can find similar free site.

Be sure to post your
answer at this forum so other can benefit it later
