As long as you apply, you don't need the so-called "approval". On the day of application, you will get the application number and application date. With the application date, you can get the protection (from the application date) as long as you authorize (that is, you say approve) in the future. So you should find a special agency as soon as possible, and ask them to help you submit a patent application before you submit it (this is the best), or at the latest before it is made public (such as publication).
In short, just submit it, whether authorized or not.
