Certifications & Apostilles - CFA Level 1 Letter for visa and residential purposes

Hello,
I am relocating to the UAE (specifically Dubai). I have been asked to provide any educational proof possible and to have this attested/certified for the purpose of obtaining my residence and working visa.

I am enrolled in the CFA Program and have passed level 1. I do not hold a university degree and my high school certificates are not currently available to me.

Has anyone had a similar experience, how did you manage to have your document attested and do you know if this is acceptable?

Thank you in advance.
