The inquiries into the community's criminal history were made in internal US Citizenship and Immigration Services emails obtained by The Associated Press.
They show the agency's newly appointed policy chief also wanted to know how many of the roughly 50,000 Haitians enrolled in the Temporary Protected Status program were taking advantage of public benefits, which they are not eligible to receive.
The programme is intended to help people from places beset by war or disasters and, normally, the decision to extend it depends on whether conditions in the immigrants' home country have improved enough for them to return. But emails suggest Homeland Security Secretary John Kelly, who will make the decision, is looking at other criteria.
"I do want to alert you ... The secretary is going to be sending a request to us to be more responsive," Kathy Nuebel Kovarik, the USCIS head of policy and strategy, wrote on April 27.

The request for criminal data for an entire community is unorthodox. The law doesn't specify it should be a consideration for Temporary Protected Status and the government has never said it would use criminal rates in deciding if a country's citizens should be allowed to stay under this program.
Introducing new criteria is likely to cause consternation among law-abiding Haitians who may feel they are being penalized for the wrongdoing of their compatriots.
He has enhanced efforts to arrest people living illegally in the United States and sought, unsuccessfully so far, to suspend refugee arrivals and temporarily block visitors from seven Muslim-majority countries. He has accused those in the US illegally of fueling criminality in the US.
It is unclear if the agency is asking such questions about other recipients of the temporary protection, including immigrants from Honduras and El Salvador.
The Homeland Security Department said Kelly has not made a final decision about Temporary Protected Status for Haiti and declined to comment on the process.
