I think it's important to be aware of the sorts of persons who were legally authorized to enter the US but who were detained at the airport (and would have been sent back, if not for the district court's stay) as a result of Trump's executive order that is claimed to be an attempt to protect the US from a repeat of 9/11.
Mr. Darweesh and Mr. Alshawi are the petitioners in this case, on behalf of themselves and the many others similarly situated:
17. Hameed Khalid Darweesh is a 53-year-old citizen of Iraq, married with three children (twenty years, fifteen years, and seven years of age).
18. Mr. Darweesh was trained and worked as an electrical engineer in Iraq. Between March 20, 2003 and September 30, 2013, he was contracted by the U.S. government to work in a variety of positions that placed him in substantial risk of being targeted, attacked and killed by anti-American militias and insurgents.
19. Mr. Darweesh’s services included: working as an interpreter for the U.S. Army 101st Airborne in Baghdad and Mosul from April 1, 2003 to January 15, 2004; working as an interpreter for the 91st Engineering Unit at the Baghdad Airport from January 20, 2004 to August 4, 2004; working as a Project Engineer for the U.S. Government Projects Contracting Office Oil sector of North Iraq from December 5, 2005 to December 1, 2006; and, working for Vessar contractors of the U.S. government from 2006 to 2011.
20. Mr. Darweesh was directly targeted twice for his association with the U.S. Armed Forces. While working at the Baghdad Airport between 2004 and 2005, the Baghdad Police entered his house, claiming they were searching for a terrorist. The Baghdad Police are widely known to be closely affiliated with anti-American militias. Shortly after this incident, two of Mr. Darweesh’s colleagues were killed as soon as they arrived at work. As a result of these attacks, Mr. Darweesh feared for his safety and decided to leave Baghdad for Kirkuk.
21. In the second instance, in July 2009, Mr. Darweesh was stopped at a market in Kirkuk where he was informed by a local shopkeeper that men were driving around in a BMW asking for him by name and the location of his house. These men returned a second time the following week, and Mr. Darweesh had strong reasons to suspect that the men searching for him were terrorists. As a result, Mr. Darweesh and his family were forced to flee to a different area of Iraq, Erbil.
22. Based on these threats and his over ten years of service to the U.S. government, Mr. Darweesh applied for an Iraqi Special Immigrant Visa (SIV) status on or around October 1, 2014.

28. Mr. Darweesh received COM Approval for the visa on January 26, 2015, in a signed statement from Lena Levitt, Refugee Coordinator of the Designee of the Chief of Mission, noting that Mr. Darweesh had provided “faithful and valuable service to the United States Government.”
Upon arrival at JFK, Mr. Darweesh was separated from his family and was denied meeting with his lawyer, who was at the airport and requested repeatedly to meet with his client.
39. Haider Sameer Abdulkhaleq Alshawi is an Iraqi national born on April 29, 1983 in Baghdad, Iraq. He studied accounting at Baghdad University, graduating in 2006.
40. Mr. Alshawi possesses the requisite documentation to enter the U.S.: an immigrant visa in his passport.
41. Upon information and belief, Mr. Alshawi was deemed admissible for a Follow to Join (FTJ) visa category F2A (joining spouse and child) awarded by the U.S. Department of State on January 11, 2017. See generally 8 U.S.C. § 1157(c)(2)(A); 8 C.F.R. § 207.7(a) (spouse or child of refugee “shall be granted refugee status if accompanying or following-to-join the principal alien”). Upon information and belief, the visa was authorized by USCIS and the State Department, documenting its approval of Mr. Alshawi’s admissibility to the United States as an FTJ Visa recipient. Upon information and belief, The U.S. Embassy in Stockholm also determined that Mr. Alshawi does not pose a security threat to the United States, and, as a result, is admissible to the United States.
42. The FTJ visa was granted to reunite Mr. Alshawi with his wife, Duniyya Alshawi, and their seven-year-old son in the United States. Mr. Alshawi and his wife have been married since 2008.
43. Ms. Alshawi worked for Falcon Security Group, a U.S. contractor, from 2006 to 2007 as an accountant. Upon information and belief, her brother also worked for Falcon Security Group in Human Resources. Mr. Alshawi heard through neighbors in the family’s community in Baghdad that, due to the family’s association with the U.S. military, insurgents thought that they were collaborators.
44. In 2010, insurgents attempted to kidnap Ms. Alshawi’s brother. A month later, an IED placed on Mr. Alshawi’s sister-in-law’s car detonated, killing her husband and severely injuring her and her daughter. Fearing for their safety, Mr. Alshawi and his wife moved from Baghdad to Erbil, Iraq.
45. Ms. Alshawi and her son applied for refugee status in January 2011. Upon information and belief, in January of 2014 Ms. Alshawi and her son were approved to travel to Houston through the Priority 2-Direct Access Program (P2-DAP). Upon information and belief, Ms. Alshawi and her son have since adjusted their statuses to that of lawful permanent residents and now live in Houston, Texas. Ms. Alshawi subsequently filed for a FTJ visa for her husband. On October 9, 2014, USCIS approved Ms. Alshawi’s I-730 petition for Mr. Alshawi’s entry. On January 11, 2017, Mr. Alshawi obtained a U.S. Visa Foil Type ZZ (Visa 93) with a notation in his passport that the foil was prepared at DHS request.
Mr. Alshawi was blocked from exiting the aircraft by CBP agents.
But, of course, Trump's EO would allow in people such as Mohammad Atta and the other identified 9/11 hijackers who were from Saudi Arabia, where Trump has business interests worth millions of dollars.
It's all very sick.
