The internal report found that forms from those applying for the program included social security numbers, addresses and phone numbers being used hundreds of times in some cases.

Parts of the report shared with Fox News Digital by the Federation for American Immigration Reform (FAIR), a conservative immigration group, showed that 100,948 forms were filled out by 3,218 serial sponsors — those whose number appears on 20 or more forms.

It also found that 24 of the 1,000 most used numbers belonged to a dead person. Meanwhile, 100 physical addresses were used between 124 and 739 times on over 19,000 forms. Those addresses included storage units. One sponsor phone number was submitted on over 2,000 forms, and there were 2,839 forms with non-existent sponsor zip codes, according to the leak.
