Is this correct ?

Je habite en Qatar

Bonjour Cynthia !

First of all, you need to know that Qatar is a masculine country in French, so you will say:
J'habite au Qatar.

Secondly, from your name, I assume you are a woman, so your nationality will have to agree accordingly:
Je suis kenyane.

I hope that's helpful!
À bientôt !
