Transfers of ICE Detainees from the
San Antonio Dro Hold Room
San Antonio, Texas
Table 1: Transfers
During the most recent 12 month period for which data are available, a total of
1,076 detainees were transferred by Immigration and Customs Enforcement (ICE)
from the San Antonio Dro Hold Room where they
had been temporarily housed to other facilities. The average
stay for these individuals before their transfer was less than a day.
This is a special ICE holding area or staging location that under current ICE detention standards is
allowed to temporarily house aliens for up to 12 or 16 hours. These types of units generally have
no sleeping quarters or shower facilities.
Transfers made up 46 percent of the 2,343 detainees who in one way or
another left this facility during the last 12 months.
This report focuses just on these transfers.
The remaining individuals who departed from the San Antonio Dro Hold Room last
year actually left ICE detention.
These individuals were deported from the country, released
under supervision while their cases was being decided, or left ICE detention for a variety of other

This report series is based upon analyses conducted by the Transactional Records
Access Clearinghouse (TRAC) at Syracuse University of 1.7 million government
records tracking each individual who passed through an ICE detention facility
during fiscal year 2015. This most recent 12 month period for which comprehensive data are
available covers October 2014 through September 2015.

How This Facility Ranks Nationally
Detainee transfer rankings. The San Antonio Dro Hold Room was one of 637 facilities
nationwide that housed ICE detainees during the most recent 12 month period. Of these
637, there were 409 facilities that had at least 10 ICE detainee transfers
last year. Excluding those facilities with fewer than 10 transfers, the
San Antonio Dro Hold Room last year ranked in the top 17 percent nationwide in
the number of individuals it transferred to other ICE facilities.
This means that 17 percent of the locations contributed the same or a
larger numbers of transfers, while 83
percent had a smaller number. See Table 1.
Average length of stay before transfer. Once detainees arrived at the San Antonio Dro Hold Room their
average length of stay before being transferred on to another ICE facility was less than a day last year.
Ranking facilities from longest to shortest detention stays for their transfer population,
this average of less than a day placed San Antonio Dro Hold Room
in the top 83 percent of all facilities nationwide.
That is, for detainees who are transferred, 83 percent
of ICE detention facilities have the same or longer average stays last year,
while 17 percent of detention facilities had shorter average stays.
Origins and Destinations
Were these detainees arrested locally? Where did those that ended up being
transferred from the San Antonio Dro Hold Room last year originate?
Information on the place of arrest was not included in the available data ICE
released. However, we can examine whether the San Antonio Dro Hold Room was
the first ICE facility in which these detainees were held.
According to ICE records, for the vast majority (97 percent) of
these detainees, the San Antonio Dro Hold Room was the first place they were
sent when they were detained by ICE.
The remaining 3 percent had been
transferred in from another ICE detention facility.
We can also look at how quickly they arrived at this facility after they were
Again, a total of 97 percent arrived at the San Antonio Dro Hold Room at some point
during the very first day they were detained by ICE. This
percentage is also based on an analysis of the most recent 12 months for which
data are available.
How soon did transfers occur? Nationally, the median number of days before an
ICE detainee is transferred to another facility was 1 days last year. That
means that half of all transfers occurred on or before the 1st day,
while half had longer stays before they were transferred on to another ICE facility. Note
that nationally the average stay at an ICE detention facility before an
individual is transferred is longer - 12 days. This is because
while most detainees have relatively short stays before ICE transfers them
elsewhere, sometimes stays are lengthy and these lengthy stays raise the average
to above the median stay.
For the San Antonio Dro Hold Room last year, the median stay before a detainee
was transferred was less than a day. This is less than the national figure.
The average stay before transfers occurred was the same - less than a day - than the median stay. As noted above,
this figure placed the facility
in the top 83 percent among ICE detention facilities nationwide in the average number of days a detainee spent before he or she was transferred.

Where did those transferred get sent? ICE currently has great discretion about
where in the United States transferred detainees are sent. For the period
covered by these data, ICE divided the country into geographic regions or areas
and assigned each to one of 152 document control offices or DCOs for the purpose
of keeping track of detainees. Available data allow us to examine whether the
transfer occurred within the same DCO or the transfer was to a different DCO.
For the nation as a whole during the latest 12 months, 54 percent
were within the same DCO, while the remaining 46 percent were to a
Table 3: Transfer destinations during last 12 months
Figure 2 and accompanying Table 3 provide some comparative figures for how the
San Antonio Dro Hold Room stacks up against this national pattern.
Last year, only 12 percent of the transfers from the San Antonio Dro Hold Room were to locations in the same
region -- facilities under the control of same ICE docket control office.
The vast majority (88 percent) of the transfers went to detention facilities in a different region (DCO).
Which nationalities predominate? Last year in the United States, individuals
from Mexico comprised the largest number of those transferred by ICE. Some 41.3
percent of all transfers recorded Mexico as their country of origin.
The San Antonio Dro Hold Room had a large proportion of detainees from Mexico - 58 percent - among their transfers.
Detainees from Mexico were also the largest single nationality group among the transfers at the facility.

Out-of-region transfers by nationality. Within the nationalities that made up
those listed in Table 4, the proportion transferred out of the region
varied from 67 percent to 100 percent.

locations outside the region.
More than one country was tied with the highest out-of-region transfer rates of 100 percent (see Table 4).
At the other end of the range, 67 percent were out-of-region transfers for the 3 transfers from Egypt.
