How we, immigration lawyers, obtain these information? It is through the American Immigration Lawyers Association. You cannot be a member unless you are an attorney in good standing. I can hardly think of its substitution no matter how large the law firm is.  What I'm trying to say is, this area really needs expertise and updates which non-member does not have access.  You should only hire a lawyer practicing immigration very seriously. 

"The beauty of immigration laws is that they change so quickly.  Like once a week, something changes like where to file, etc. You have always something to learn." That's what I said to my classmate at the conference.

"Why is it the beauty?"

"Well....You never get bored. There is always something to learn"
