National Review is of course more on the right, but the argument they provide for why he is legal seems fair. Now if they deem Code 1182 (f) unconstitutional that's another matter altogether
I quote:
"(f) Suspension of entry or imposition of restrictions by President
Whenever the President finds that the entry of any aliens or of any class of aliens into the United States would be detrimental to the interests of the United States, he may by proclamation, and for such period as he shall deem necessary, suspend the entry of all aliens or any class of aliens as immigrants or nonimmigrants, or impose on the entry of aliens any restrictions he may deem to be appropriate."
of course this conflicts with 1152 (1) A, and since 1152 came after... it should in theory be an amendment upon the first, HOWEVER
Except as specifically provided in paragraph (2) and in sections 1101(a)(27), 1151(b)(2)(A)(i), and 1153 of this title, no person shall receive any preference or priority or be discriminated against in the issuance of an immigrant visa because of the person’s race, sex, nationality, place of birth, or place of residence.
Now 1187 a (2) A under Obama DOES actively discriminate upon country of origin.
(2) National of program countryThe alien is a national of, and presents a passport issued by, a country which—
(A) extends (or agrees to extend), either on its own or in conjunction with one or more other countries that are described in subparagraph (B) and that have established with it a common area for immigration admissions, reciprocal privileges to citizens and nationals of the United States, and
AND
1187 a (12) also under Obama
(i) the alien has not been present, at any time on or after March 1, 2011—
(I) in Iraq or Syria;
(II) in a country that is designated by the Secretary of State under section 4605(j) of title 50 (as continued in effect under the International Emergency Economic Powers Act (50 U.S.C. 1701 et seq.)), section 2780 of title 22, section 2371 of title 22, or any other provision of law, as a country, the government of which has repeatedly provided support of acts of international terrorism; or
WHOA: OBAMA DID THE EXACT SAME THING.
So there's my two cents. AND the law
