I thought that this quote below from raf.mod.uk put me in the "able to apply" bracket.
UK Resident less than 3 years
If you have been resident in the United Kingdom for less than 3 years, but fall into one of the following categories then we will need to complete further checks on your eligibility during the application process. In the meantime, you should register you interest as normal.
- You spent time abroad for travel/ study gap year reasons.
- You lived abroad because your parents were employed by the UK government (including HM Forces) in a foreign country.
- You are a British citizen with at least one parent who is a British citizen and you lived with your parents abroad and you attended secondary school within the European Economic Area or a Commonwealth Country.
If you do not fall into one of the above categories, then you are ineligible to apply to the RAF at this time.
