Approval to process

Hey, withdrew my application to join the army a few months ago as I decided I wanted to join the navy as an AET.

As I served previously in the army with not the most extensive service - I joined at 16 and was immature at the time and to be honest missed home too much. I was discharged as 9.414 - not required for further army service, however, they let me reapply last year and was due to start pirbright for phase 1 in march but got talking to the navy at the afco and after a long chat decided to go with them.

I am now going through the process and awaiting approval to process I'm just wondering if there would be anything that would prevent me from attaining this?
