Some groups involved in SDN and NFV joined the chorus of tech companies that oppose President Trump’s ban on immigrants from primarily Muslim countries.

In case you’ve been living under a rock: On Friday, President Trump signed an executive order suspending entry to the United States for 90 days for citizens from seven countries: Iran, Iraq, Libya, Somalia, Sudan, Syria, and Yemen.

Leaders of major tech companies such as Apple, Google, and Netflix swiftly condemned the order. And the co-founder of Google, Sergey Brin, who is an immigrant from the former Soviet Union, even attended the protest at the San Francisco Airport over the weekend.

It’s well documented that tech companies tap the talents of immigrants from all over the world, and they’re concerned about restrictions on their talent pool.

There were a few comments regarding the immigration ban among the organizations that SDxCentral covers.

“For the Linux Foundation, openness is both a part of our core principles and also a matter of practicality,” writes Jim Zemlin, the Linux Foundation executive director. “The administration's policy on immigration restrictions is antithetical to the values of openness and community that have enabled open source to succeed.”

Linux’s creator and a Linux Foundation Fellow Linus Torvalds, immigrated to America from Finland.

A blog posting penned by Jonathan Bryce, Mark Collier, and Lauren Sell with the OpenStack Foundation notes that the executive order makes it difficult for the open source group to host conferences in the United States, where some contributors may not be able to attend.

OpenStack has two scheduled events in the next six months, one in Atlanta and one in Boston. “This executive order could impact some community members‘ ability to travel to Atlanta and Boston, but unfortunately it is too late at this point to change the location of these events,” according to the blog. “The following three OpenStack Summits, however, are now scheduled to occur outside of the United States.”

Citrix Chief People Officer Donna Kimmel and Citrix General Counsel Tony Gomes sent an email to employees, saying, “We hope the administration will revise the executive order and reverse the hardship it is causing to employees, their families, our customers, and potentially our business."

The email also noted “there is uncertainty around how the executive order is being applied and who is impacted.” The executives advised that even lawful permanent residents of the United States should consider deferring international travel until the applicability of the executive order is clarified.

A Red Hat corporate blog posting reads, “We are looking carefully at Friday's U.S. executive order on immigration and how it will be implemented. From what we see so far, we are concerned that the changes are inconsistent with Red Hat's values, including diversity.”

Finally, a short Intel corporate blog posting reads, “We are providing support to potentially impacted employees, all of whom are in this country lawfully. As a company co-founded by an immigrant, we continue to support lawful immigration.”
