Engineering students have described to me how some of the foreigners get into another course of study so they can stay here. I personally know an engineering grad from India who has been allowed to stay; here in NJ the number of Asians being added to our population is incredible. I believe they are legally allowed to stay here (and work) while they complete paperwork for citizenship.
I don’t believe any foreigner from any country is being forced to leave - at all.
That's good. Asians, generally, if they come through the schools, are good additions. That doesn't include Arabs and Pushtuns and other Moslem Asians, though. It definitely includes Hindus and Southeast Asians. Chinese are good, too, but come with some other problems, political in nature. Industrial spies come among them. And Hindus and Buddhists and East Asian animists are not incompatible with Christianity and civilization as Moslems most definitely are.
I had known some foreign students in the 90s and their complaint was as I described. It has been a while now. I hope that the policy has quietly changed back to be more as it was once. Now if we could stop the wholesale hauling of Moslem "refugees" into the country and uneducated poor people from cultures that don't value education...
And we don't need Moslem engineers and scientists, either. They are too apt to return to use their training to build better explosives for their children to wear or stay and enable our "lone wolves" to do a better job.
