About the company
Shan Y Tsen, a sole proprietorship based in San Francisco, California, provides translation, interpretation, and cultural advisory services to the Department of State as a prime contractor. The vendor is minority-owned, woman-owned, and self-certified as a small disadvantaged business; the company competes in the full-and-open market without set-aside designations across its federal footprint.
All 44 recent awards are prime BPA calls issued by the Department of State Bureau of Administration for language services supporting diplomatic engagements, foreign policy initiatives, Taiwan cooperation programs, and G20 participation. Individual task orders range from $1,600 to $25,200 with firm fixed pricing. Work is performed in Washington, D.C. The vendor holds three active Blanket Purchase Agreement vehicles with the Bureau of Administration: the most recent BPA (190PRL25A0668, awarded October 1, 2024, $250,000 ceiling through September 30, 2026) carries 17 task orders valued at $183,000; a prior vehicle (190PRL24A0668, awarded October 1, 2023, $150,000 ceiling through September 30, 2024) supported 7 task orders worth $114,000; and an older agreement (190PRL22A0668, awarded October 1, 2022, $150,000 ceiling through September 30, 2023) generated 3 task orders totaling $16,000. Representative recent awards include a $7,828 call dated October 1, 2025 with performance due May 9, 2026; a $13,596 call also dated October 1, 2025 completing November 21, 2025; a $24,800 call dated October 1, 2024 completing January 25, 2025; and a $22,000 call dated October 1, 2023 completing September 27, 2024.
Customer concentration is singular: the Department of State Bureau of Administration accounts for 29 awards ($924,000 combined potential value) and the broader Department of State for an additional 7 awards ($73,000 combined potential value), together representing 82% of award count and 98% of combined potential value. Combined potential value across all 44 awards totals approximately $1 million, with $372,000 obligated to date (36% of potential). Activity grew from 4 awards in 2021 to a peak of 11 in 2024; 2025 saw 7 awards as of October. The vendor operates exclusively as a prime contractor with no subcontract footprint and does not hold positions on government-wide vehicles or multi-agency IDIQs; all work flows through State Department BPA vehicles renewed annually with October 1 award dates.
