Thank you ksand24!
Reason for seeing a solicitor is because once I start the SET (AF) application, I am greeted with this:
"Use this form to apply to settle in the UK as a discharged member of HM Forces, or as a partner or child of a serving or discharged member of HM Forces.
HM Forces means a member of the Royal Navy, British Army or Royal Air Force and includes a person who was a member of HM Forces but was discharged within the period of 2 years prior to the date of this application."
28 days before my visa expires would be October 30, 2022. My husband would be discharged April 3 2020. So this would be out of the 2 year period prior to the date of the application right?
