"In order to strengthen our immigration system, protect national security and better serve American workers, we must suspend the issuance of all H-1B visas for 180 days to complete a comprehensive investigation and audit of pervasive allegations of abuse of the program," said Republican presidential candidate Ted Cruz as he rolled out his immigration reform plan.
"New allegations detail appalling abuses of the H-1B visa program - a program meant to create American jobs and spur economic growth. I will suspend the program for 180 days to investigate abuses," said Cruz whose popularity ratings in the last few weeks have increased nationwide.
"The purpose of legal immigration should be to grow the economy, not to displace American workers. Under no circumstances should legal immigration levels be adjusted upwards so long as work-force participation rates remain below historical averages," he said.
Cruz sought to end birthright citizenship. "Birthright citizenship was not intended to legalise the children of people who are breaking the law by entering and staying in the country illegally. I will take steps to pass legislation or a constitutional amendment to end it," Cruz said.

"A Cruz administration will enforce existing protections for American workers and amend the H-1B visa program to fulfill its original purpose," he said.
Calling for creating a "layoff cool-off" period for all H-1B visa applications, he said companies must wait one or two years between laying off a worker and bringing in any H-1B foreign workers to ensure that the program is not used to displace American workers.
Under his plan, Cruz said companies will provide sworn statements and documentation that detail their efforts to hire Americans before requesting foreign workers through the H-1B visa program.
Individuals who make false statements in these affidavits will be subject to perjury charges, he said.
