Previously, a group of fourteen Indian students, who were on their way to join universities in the US were deported after being interrogated by the FBI.
India's External Affairs Ministry has taken up the matter with US officials.
Fake universities and deported students
Why were the students stopped?
Air India officials stated that since the universities the students were joining were black-listed in the US, they were likely to be deported as soon as they landed.
They said the action was taken after receiving a communication from the US Customs and Border Protection agency.
Air India said they didn't want the students to be "inconvenienced" or that they lose their money.
Universities deny AI's 'black-list' claim
The two universities that the deported students were to join were Silicon Valley University at San Jose and North Western Polytechnic College, Fremont, in California.
Air India cited a US Customs and Border Protection agency communication, that stated that these universities were under scrutiny.
However, the Universities have stated that they are not black-listed by Customs or any other US government entity.
