The ASUs listed above were included in our survey. It was our intention to survey 100 percent of the ASUs. However, we had difficulty constructing a definitive list of ASUs because INS has no standard procedure for establishing an ASU and does not have one clear definition of what constitutes an ASU.

ASUs listed above are considered ASUs by INS headquarters, the corresponding regional office, and the ASUs themselves. These ASUs have criminal investigators who work exclusively on anti-smuggling cases. Sub-offices are not listed.
