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.

See: https://french.kwiziq.com/revision/grammar/use-en-with-feminine-countries-and-aux-with-masculine-countries-to-say-in-or-to-prepositions

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

See: https://french.kwiziq.com/revision/grammar/how-to-express-your-nationality-changes-whether-youre-a-man-or-a-woman-adjectives

I hope that's helpful!
À bientôt !
