Immediately enact a one-year moratorium on permanent immigration and student visas.
Resume immigration after that at approximately 1/8 to 1/4 the previous level, without quotas.
Enforce common-sense profiling at airports.
Impose a one-year moratorium on new H1-B visas, too. Likewise, cut those levels afterwards, as well.
Your ideas are not good enough! A total ban on immigration for 25 years is necessary. After that an extremely limited lifting of the ban for certain individuals from countries we designate. End all politcal asylum. Removal of all illegals from America, especially those from Latin America and the Islamic world. Announce to the world that America will no longer tolerate any illegal border jumpers. And also declare that America will no longer be open to immigration. No more student visas. All visa violaters immediately deported to country of origin.
