SUMMARY: Embassy Montevideo conducted a validation study of B1/B2 visa issuances to Uruguayan nationals using information from DHS's Advanced Targeting System (ATS),Arrival Departure Information System (ADIS),and follow-up telephone calls, Post identified an overstay rate of less than one percent. END SUMMARY. ¶2. B1/B2 applicants comprise approximately eighty percent of Montevideo's annual NIV workload. Using a random number generator, Post generated a sample group of 1,089 visas issued between 01/01/08 and 12/31/08, approximately 10% of the 10,800 B1/B2 visas issued to Uruguayan nationals during that period. The sample was submitted to CA/FPP for assistance in checking arrival and departure information via ATS and ADIS. The ATS and ADIS data eliminated all but 29 cases which were then checked with follow-up phone calls made by the Fraud Clerk. The results indicate that Uruguay has an overstay rate of well under 1% and that there is no discernible pattern in the demographics of people who overstay. The confidence interval was calculated to be +/- 0.6% or 99%+ confidence in the results. ¶3. For the period in question, Post's refusal rate for Uruguayan nationals soliciting B visas was 7.16%. ¶4. Post thanks CA/FPP for their assistance with ATS and ADIS. MATTHEWMAN
