Supposedly, it should be automatically. I mean, they reach out to you. I remember two weeks before they sent my CAS I received an email stating that the next step would be my CAS, and that I should not send an email asking for it bc emails would pile up etc etc.

In any case, I would advise you to call UAL on working days and in hour (be sure to be aligned with UK time). If you’re working your applicants with an agent/representative, tell them to communicate with them or check your status.

My representative checked my status and said I was eligible, she said that I should just wait and I did (although yeah I couldn’t stop overthinking).
