Panama vs. UAE Residency: Is Panama Still Worth It?

I reached to Saxo and they wouldn't open accounts for Panama residents. However Charles Schwab has their international expat service so it should work there,

Can you share some example because from my experience, they have the same name but are managed differently and you can't open an account in another country even if you are a client of bank xyz in the other country. (ex scotia bank in Panama won't open an account for you just because you're a Scotia bank client in Canada).

any example?
