What level can I choose my advanced class?
In Star Wars the old republic, you choose a class at character creation and later you get to choose an advanced class (such as gunslinger for smuggler). What level does that happen?
You can make the decision when you leave the starting planet. You also need to be at level 10, you may not be level 10 at when you reach this point so you'll need to go back if you leave that area.
To leave the starting planet/area you need to complete all the story quests.
Once you have hit 10 you will be allowed to move to fleet then go to either Corusant or Dromund Kas. When you arrive on fleet you can choose your advanced class at your class trainer. Then they will tell you who to go to. Hope that helps guys.
