I Googled but couldn't verify this claim; what's your source?
I heard Senator Cruz say it on a radio news show going over quotes of the day. But here is at least one link:
Here's what Cruz said on H-1B when in the Senate.
There is currently a serious shortage of workers in the fields of science, technology, engineering, and math, yet every year we send thousands of high-tech graduate students back to their home countries to start businesses and create jobs. This makes no sense.
Donald Trumps comments during the News Conference when he signed the GOP Pledge, on 9/3, use almost these exact words. I can't find a written transcript of that either, but the videos of it are around. About 40 min long.
For further evidence, Google, or Bing, Cruz, Sessions, and Immigration together, and look at all the times they have been in lockstep on the issue.
Trump, Sessions, and Cruz are united on immigration reform.
Sorry, I usually can provide direct evidence, but I can't find a copy of what I heard in Cruz's speech Q&A that day. If I run across a transcript, I'll get you a link, or a copy.
