What is a Gyosei Shoshi Lawyer ?

In addition to attorneys (bengoshi), there are different legal specialists in Japan who are qualified by the Government. Each of them have their own specific specialization, and the Gyosei Shoshi Lawyers cover rather large fields from administrative procedures to everything concerning the rights and obligations.

That is why each Gyosei Shoshi Laywer has specialized fields that could be completely different from someone else of the same profession.

Among the legal specialists, Gyosei Shoshi Lawyers are the only ones who are authorized by Immigration to proceed visa and status of resident's application on behalf of their clients, until the same title was granted to attorneys (bengoshi) in 2004.
