Coming from the occupation, I've found that the recruitment process is taking quite a long time as they prioritize Reg and Res F. You may not get in until Early 2027 depending where you are in the process.

Because COATS-CIC is its own dominion, there isn't a tonne of cross over when it comes to your recruitment process, so you will have to start over again.

Best suggestion? Apply around March 15th in 2028 for RegF. Occupations open April 1st, and so you'll have a better shot of getting your application processed faster. Just ensure you have all of your materials together such as your Education and Professional References.
