Yet, the SE Asian workers in the Gulf aren't given that title. If you are an American, European, or Australian you are an expat. If you are Indian you are just a migrant worker.
Are Indian business executives ‘migrant workers’?
Since when is India in South east asia?
Even in the Gulf countries, in many contexts, expat is used as a synonym for "white people", or at least people from rich countries. I used to live in Kuwait. In other countries it refers to any foreigners.
