BERKELEY, Calif. (AP) — The number of applications for visas used in the technology industry soared for a second straight year, raising “serious concerns” that some are manipulating the system to gain an unfair advantage, authorities said Friday.

There were 780,884 applications for H-1B visas in this year’s computer-generated lottery, up 61% from 483,927 last year, U.S. Citizenship and Immigration Services said in a message to “stakeholders.” Last year’s haul was up 57% from 308,613 applications the year before.

Each year, up to 85,000 people are selected for H-1B visas, a mainstay for technology giants such as Amazon.com Inc., Google parent Alphabet Inc., Facebook parent Meta Platforms Inc. and International Business Machines Corp.

Last year, the government began requiring workers who won the lottery to sign affidavits stating they didn’t try to game the system by working with others to file multiple bids under different company names, even if there was no underlying employment offer.
