Developing Strong Letters of Support for Grant Applications

A resource guide for law enforcement agencies

Many federal, state, and private grant programs require applicants to demonstrate collaboration with partner agencies through letters of support, certifications, or memoranda of understanding (MOUs). Rather than simply requesting a letter, applicants can significantly improve both the quality and timeliness of these documents by providing partners with a draft letter or concise fact sheet that summarizes the project.

This approach reduces the burden on partner agencies, ensures accuracy, and helps produce stronger documentation that aligns with grant requirements.

Applicable to All Grant Program Partners

Although some grants require support from specific organizations (such as a U.S. Attorney’s Office or federal agency), this practice is recommended for all project partners, including:

  • U.S. Attorney’s Offices
  • Federal law enforcement agencies (FBI, ICE, ATF, DEA, Homeland Security Investigations, U.S. Marshals Service, etc.)
  • State law enforcement agencies
  • District Attorney’s Offices
  • Probation and Parole
  • Emergency Management
  • Prosecutors
  • Local government officials
  • Behavioral health providers
  • Victim service organizations
  • Universities and research partners
  • Faith-based organizations
  • Nonprofit organizations
  • Technology partners
  • Regional task forces
  • Any organization providing personnel, equipment, training, referrals, or operational support

Example:
Federal funding opportunities such as the Department of Justice Bridging Immigration Deficits Encountered Nationwide (FY 2026 BIDEN) Program and the Model Cities Initiative require applicants to coordinate with the appropriate United States Attorney’s Office. The BIDEN program also requires documentation confirming participation with U.S. Immigration and Customs Enforcement (ICE) under a 287(g) Task Force Model Agreement.

Providing a draft letter or project fact sheet allows these organizations to quickly verify the information, make edits as needed, and return a signed letter before the application deadline.
