Why is Binance discriminating based on Nationality instead of Residence?

Since last december there was a requirement for Binance users to reverify their accounts. This has lead to some strange consequences.

I am a national by birth of "nation X" but a legal tax paying resident of "nation Y". Having used a passport of "nation X" as a means of verifying my identity and a proof of address of "nation Y" as a proof of residency apparently doesn't qualify you as a Binance user of "nation Y". However, I do find in the personal verification, my residential country/region to be "nation Y". What I mean with -doesn't qualify you as a binance user of "nation Y"- is that I cannot deposit Fiat of "nation Y" because of my "nation X" identity. Even though I am a resident of "nation Y".

I have spoken to customer support on binance however the person seemed reluctant to help or didn't know what to do. Can someone please advise me?
