B61,
I would suggest this to your student, Ryanair is the really the only option for a low houred UK national with an EASA license, and even then that will be flying for Ryanair from a UK base.
As a UK national he/she (best add whatever they may identify as) wont have the automatic right to work in Europe, the chances of getting a visa in the next few years will be non existent.
If the exams were completed after 31/12/2020 they wont be recongnised by the UK CAA for UK Part FCL issue.
Even when the UK was in EASA the language requirement imposed by alot of EU operators stopped UK applicants applying. So why on earth do they think they will end up flying for an airline in the EU on an EASA license. This happens alot UK students are getting this obsession with the need to have an EASA license, when outside of Ryanair it will be near useless for them.
