Tech companies have been fretting and fuming since Donald Trump announced a blanket ban on immigration from select countries.

While CEOs of many of these companies have strongly condemned the order, some have decided to fight the order in their own way. Others have already initiated legal proceedings.

Alphabet (Google), Apple, Facebook and other companies have also banded together to draft a letter to Trump, reports Recode.

In the letter (it’s still a draft), the companies seem to be appealing to Trump to do the right thing. They want him to understand that America has always been a land of opportunity and that, “As entrepreneurs and business leaders, our ability to grow our companies and create jobs depends on the contributions of immigrants from all backgrounds.”

They state that they believe in the need for increased security and “welcome the changes” Trump’s administration has made. However, they say that, “a blanket suspension is not the right approach.”

Continuous evaluation and improvement is needed, they add.

The letter also mentions the Deferred Action for Childhood Arrivals (DACA) program and points out that it would eliminate these ‘Dreamers’ ability “to work and live without the fear of deportation.”

The draft ends with a statement that claims that these companies share in Trump’s “commitment to growing the American economy” and that they recruit thousands of Americans as well as “some of the most talented people from abroad.”

These companies are also considering legal proceedings against Trump’s order, which might actually come to pass if the letter fails to make an impact.
