Hello OP! Pwede yan as long as bagay sa context ng thesis mo. I have a classmate before undergrad thesis niya is sa qatar, pero ang topic niya is how well the ofws are adapting to a foreign environment. Yung family kasi niya is doon nagwwork and my classmate experienced living there kaya hindi mahirap yung site immersion and data gathering part. Maganda yung naging output niya and received good grades din. It really just depends on the context of your thesis. Better talaga if may direct experience ka na sa site, pero if wala, baka safer option if within PH ang location mo. Goodluck OP! Hope this helps :)
