The estimated time for processing a Full Access level application usually takes a few minutes to process if all information that is submitted is up-to-date and accurate.
At Blockchain Exchange, we pride ourselves on having a fast onboarding process. If there is an issue with the application, users can expect to receive a message from the Blockchain Exchange support team within 24 hours, where we may request follow up information or documents (i.e. resubmit a picture if it was not clear enough, or confirm their names if there was a spelling error).
If you are having issues having your application approved, you can submit a support ticket here.
