The entire expenses and charges of the E2 visa hinge on whether you are currently having residence within the U.S. or outside. In reference to the people who have secured work within the U.S. under a special visa grant, you'll just file an I-129 and have your status changed the instant your petition is allowed.
Contrasted to this, if you're currently having residence and dealing outside the U.S., you need to first bear with the long consular processing. This is achievable with the application with the U.S. consulate or embassy in your home country and also the determination and conclusion of an interview conducted by a consular officer.
