The U.S. Department of Homeland Security's Customs and Border Protection, specifically the U.S. Border Patrol, is issuing a Request for Information (RFI) to identify potential sources for Mobile Portfolio sustainment support. This RFI is for market research and planning purposes only, not a solicitation or commitment to award a contract. Interested vendors are asked to review the attached draft Statement of Work, which covers program management, logistics, quality control, transition planning, sustainment support, deliverables, and Contract Data Requirements List items. No performance location, budget amounts, or submission timelines are specified in the description.
