Pure lunacy
1.Any one can apply to visit or emigrate to the US. Whether you get in or not depends entirely on 2.meeting the criteria
3.No conspiracy, just lots and lots of paperwork, simples
4.April 1st was four weeks ago
1-2 not anyone.. if your name appears in secret service lists for some reason, you will be rejected and if your name appears to be in more crtirical lists you will be arrested the moment you step your feet from the plane..
and muslim religous groups are already in list .. with the exception of few which are already supported and armed by the service (hence meeting the criteria)
3.I'm afraid after the last century the world is no more alice wonderland Al.. my country is being accused (by universal human right organizations) to permit secret service airplanes only for transit usage of air fields.. they were carrying obviously "enemy" religous cargo

(and the cargo was brought to a specific island to "ask some questions")
4. I never joke to anyone on april 1st..
