Tech giants are leaving the country in droves in 2021, and many of them aren’t even coming to the US, according to the biggest tech companies in the country.

The Wall Street Journal has the list of companies that will likely leave, with an estimated 40% of the top tech firms announcing plans to leave the US by 2021.

The companies are:Boeing (BA), Google (GOOGL), Salesforce (CRM), Facebook (FB), Twitter (TWTR), Dropbox (DLTR), SalesForce.com (SRF), Oracle (ORCL), LinkedIn (LNKD), PayPal (PayPAL), Yelp (YELP), Zynga (ZNGA), Twitter.com/Yahoo (TWMJ).

In a separate report, Bloomberg News cited two unnamed sources who told the newspaper that tech giants will leave the country by 2021, including Facebook, Apple, and Netflix.

Bloomberg cited two sources who said Facebook and Apple have announced plans to stay in the US.

Facebook CEO Mark Zuckerberg has said he will leave Facebook.

The tech companies are leaving because of regulatory issues.

Companies must submit detailed plans to Congress outlining how they plan to leave if they want to remain in the United States, and the rules for companies to leave depend on whether they have at least five employees and 100 employees in the state where they’re headquartered.

The top tech companies have made their intentions clear, however.

Twitter CEO Dick Costolo announced in June that he plans to join Facebook in 2020.

“We’ve been saying for a while now that we will be staying in the U.S. by 2021,” he said in a statement.

“I’m glad to have that opportunity to join this team.”

Boelson Inc. (BOO) CEO Peter Ostrom said in January that he was considering moving to California to start a business.

He said he was planning to retire from his role as CEO of Boeing.

Twitter co-founder Jack Dorsey said in June he was “proud to be in the States,” and Facebook CEO Sheryl Sandberg said she would be moving to New York.

Microsoft Corp. (MSFT) CEO Satya Nadella said in September that he and his wife, Kara, will move to Washington state.

And in June, Facebook’s Marissa Mayer said she was considering a move to the Bay Area.

Ostrom has said in the past that he’d like to continue working at Facebook, but he also has expressed skepticism that he can stay in Washington and that he should work more for other companies.

“In my view, it’s a very good thing for the United Kingdom to get a strong tech team here and a strong presence in the world,” he told Bloomberg.

“And that is where the American workforce is going to come from.”
