I did not. I hired the 2 candidates (of many interviewed) that were best qualified to perform the duties for the positions. I suppose I could have searched longer and held out for a US citizen, but I did not have that luxury due to a need to stay competive with the products we are developing. If we are not competetive, we eventually go out of business, and 40 people (most of them US citizens) lose their jobs and the ability to support their families.
