Here are their opinions:
Sharia in America: "51% of U.S. Muslims (1.5M) ... polled believe ... that they should have the choice of American or Sharia courts" (1)
Reject U.S. Law: 61%. Only "39% of (U.S. Muslims, ~1.2M) said that Muslims in the U.S. should be subject to American courts." (1) That means the other 61% (~1.8M) of U.S. Muslims believe they should not be subject to American courts.
Sharia Superiority: 33% of U.S. Muslims (~1M) believe that "If Sharia conflicts with the U.S. Constitution and the Bill of Rights", then Sharia "should be considered supreme." (1)
Violence against First Amendment Rights: 29% (~900,000) U.S. Muslims agree that "violence against those who insult the prophet mohammed, the quran, or the Islamic faith is sometimes acceptable." (1)
Sharia by Jihad: 11% of U.S. Muslims (~330,000) believe that Sharia is "The Muslims god allah's Law that Muslims must follow and impose world-wide via Jihad" (1)

Keep in mind that the bias of respondents should be to shade their answers to be more acceptable to other Americans, lest they become the targets of legal investigation for their subversive opinions. Therefore, the results above should be considered the bare minimum, and the real opinion of American muslims is likely worse than shown.
Not a single Muslim should be able to meet the requirements for citizenship since they refuse to, in fact they can not, acknowledge the Constitution as the law of the land.
