How long does it take to find out if the USPTO accepted my application for the exam?

Generally, from the time the OED receives your application, it can take anywhere from 2-6 weeks to hear back concerning your status. If you are a US citizen, with a bachelors degree in one of the “approved” scientific / technical skills, the process tends to go faster than if you require investigations into the merit of your coursework (those who don’t have a bachelors degree in a science / technological field of study).
