Seeking Help: How to Find Data on Tamil Nadu Expatriates Moving Abroad?

I am very particular about the discussion to know how many people, on average, might have moved as expatriates (employees moving from their home country [India] to the host country [foreign country]) for projects in the client place from the Tamil Nadu region. According to research on overseas economics, language barriers often deter people from moving abroad, especially in South India, where individuals struggle with cultural shock and language barriers.

Since I am linking emotional intelligence to expatriate mental health, I have tried to obtain the perfect data on expatriates moving abroad by exploring sites such as NASSCOM, PwC, IBEF, and embassy websites. However, I couldn't find the data on the number of expatriates in overseas countries.

Dear Friends, I kindly request your help in guiding me on how to retrieve expatriate data or kindly sharing the information.

Thanks and Regards,
R. Venkatesh

I am an Indian expatriate based in a Southeast Asian country. Now, the Government of India has made it mandatory to register with the Indian embassy the moment you migrate for a job to any country, and this registration is done online. If the registration is not done, then the expatriate cannot avail of any services from the embassy, including passport renewal, notarization of documents, etc.

Government Registration Requirement

The Ministry of External Affairs has this data with them along with all the information, including the vocation of the expatriates. You may approach them, and I am sure there could be some modality to get the details. You could also contact the government agency, Overseas Manpower Corporation (OMPC), and they will be able to help you.
