Security Clearance for Conditional Release

Hello everyone,

I have completed my 6-year contract with the Army Reserve and am currently in the IRR at the moment. I’m trying to submit a conditional release request to join the Navy and become their officer via their OCS program. My request got denied by some people at HRC. They said that I cannot transfer to another component since I don’t have an active security clearance, and I would need to initiate a process to update my clearance which may take another 6-12 months. Is this something legitimate? Because I could not find any regulation saying that I need to have a security clearance to have a conditional release approved. Thanks for any valuable insights.
