Currently, more than 17 million Indians are living abroad. While the exact numbers of nationals who will require repatriation are not known, it is estimated that the number could rise to a million.  

In March, External Affairs Minister Subrahmanyam Jaishankar asked Indians abroad to avoid returning until the COVID-19 situation subsided. India has now entered a third phase of lockdown, after easing some restrictions. 

During the first phase of repatriation from May 7-14, 60 commercial flights are set to bring back some 15,000 citizens from 12 countries, according to local media. About half of the flights are expected to be operated from Gulf countries, including the United Arab Emitrates (UAE), Kuwait, Oman, Qatar, Saudi Arabia and Bahrain.

Flights would also bring passengers from the US, UK, Singapore, Malaysia, Philippines and Bangladesh.   

Citizens hoping to be repatriated in the first phase would strictly be on a payment basis. The price of travel fare is unclear as of now.

Flight arrivals in India have been distributed across 10 states, with most of the air traffic going to the capital, Delhi, and the southern states of Tamil Nadu and Kerala. 

The Finance Minister of Kerala, one of the states with the highest migrant populations to the Middle East, tweeted that the state expected 500,000 migrants to return.

The first flights planned were from Abu Dhabi, Dubai, Riyadh and Doha. The massive repatriation was planned after Indians stranded abroad appealed to the government for their return.

The Gulf countries have one of the highest Indian migrant populations, with an estimated 8.5 million Indian workers spread across the region.  

Indian embassies and high commissions are currently preparing lists of citizens who are in distress. More than 200,000 people have already registered a desire to return from the the UAE alone.  

Due to the coronavirus lockdown and its economic impact, as well as an ongoing oil crisis, many migrant workers have been left without jobs.
