The Times of India reported that the US Justice Department had charged the four with one count of conspiracy to commit visa fraud. They were released on bail of US$250,000.
The charge against them carries a maximum term of five years in jail and a US$250,000 fine.
India is the biggest recipient of H-1B visas, with nearly three-quarters of the annual quota of 85,000 going to its citizens who work predominantly in the tech industry in the US.
The complaint claimed applications for H-1B visas had been lodged by Procure and Krypto, saying that the applicants in question had already secured employment with Client A.
But the chargesheet said no positions as claimed existed at Client A and the applications were a means of fraudulently obtaining the visas.
The chargesheet claimed the four used the fraudulent applications to build up staff who could then be hired out to other companies without having to wait for the visa process to be gone through.
This, it was said, would give them an advantage in the staff supply sector which has plenty of big names competing for business, among them Infosys, Tata Consultancy Services, Cognizant and Wipro.
Earlier this year, the US made changes to the H-1B visa system which had been flagged since the 2016 Presidential election brought Donald Trump to power.
One change was an estimated increase of up to 16% (or 5340 workers) in the number of selected petitions for H-1B beneficiaries with a master’s degree or higher from a US institution of higher education.
The second was that any firm applying for an H-1B must first register with the US Citizenship and Immigration Services; only companies which were selected could then apply for the visa.
