In most cases, no. If you are referring to a permit to carry a concealed weapon, there are still places you may not take a firearm. While the law varies from state to state, places that are restricted usually include courtrooms, jails and prisons, schools, bars, and Federal properties such as the Post Office, military facilities, etc. Firearms may not be taken past the secured areas at airports.
You need to define the term gun license. In most of the US there is no license to own a gun. Some states require a license to carry a gun. others to carry a gun concealed. There is also a license to make or sell guns. All are different and have different procedures.

In states that require them, it is a license to own (not to carry concealed) a gun.
It depends on several factors; Where you are located and exactly what you mean by "gun license." Do you mean a license to carry a gun? A license to purchase a gun? A license to build guns?
There is no such thing as a gun license in the US. There are concealed carry permits/licenses and dealers licenses.
You can apply but not only will you not get a license to carry, you will not be issued any firearms license.

It depends on what you mean. If you mean a federal carry permit, in the U.S. there is no such thing. If you mean a FFL, that is a business license (basically) and has nothing to do with carrying a gun, only selling them.
