Hello! What licenses are needed (or most popular)to start an Agents career?

In the United States, each state has it own licensing requirements to sell real estate. Most agents have a "sales license" and with advance training and experience there is also an "Associate Broker" license and a "Principal or Designated Broker" license. The last one is usually the owner or manager of the company.

Were you looking at getting a license in a particular state?

A license to sell real estate would be a good place to start.
Call or go online to your states licensing department, or whatever it's called in the USSR.
You're asking how to be licensed in the USSR on a generally American (USA), forum.
In Texas it's TREC, "The Texas Real Estate Commission".

BTW, how's your war going, ours is going pretty good.

That's too funny -- in a twisted sort of way.
