Well Walker’s the only one I’ve seen that wants to limit legal immigration as well as illegal. I don’t see Cruz’s position at that site.
here are all the ratings on numbers USA. Walker has the highest rating.

Positions 10. and 11. of Cruz on Immigration
10. End Visa Lotteries-institute safeguards that will prevent importation of foreign workers any time they would threaten the jobs or depress the wages of American workers.
11. Reduce Total Immigration- Until 1970, the U.S. immigration tradition was an average of around 250,000 a year; since new legislation in 1990. it has averaged 1,000,000 a year. More than 38 million foreign workers and dependents now live in the U.S. At current rates, immigration will add more than 100 million additional people to the U.S. population by 2060. This government-forced rapid expansion will require huge increases to energy, roads and other infrastructure and services.
