Advance Notice Requirements

It is essential to ensure that research vessel clearance requests for marine scientific research in foreign coastal states meet stated leadtime requirements, which may vary. All requests should be submitted to the Department of State in compliance with the "UNOLS Handbook for International Operations of U.S. Scientific Research Vessels", and should reach the Office of Ocean Affairs (OES/OA) at least one month earlier than the stated prior notice requirements of the foreign coastal state. This is to allow time for Department of State processing of the request through the U.S. Embassy to reach the foreign ministry in compliance with foreign requirements. The following are stated lead-times (plus one month processing) for various coastal states:

  • 7 months Argentina, Australia, Brazil, Chile, Colombia, Fiji, Iceland, India, Indonesia, Ireland, Italy, Mexico, Morocco, Nigeria, Portugal, Senegal, Spain, Turkey
  • 5 months Ecuador, France, Peru, Venezuela
  • 4 months Belize, Denmark, Guyana, Honduras, Netherlands, Oman, Panama, United Kingdom
  • 2 months Canada, Sweden


All other requests for foreign coastal states which have not stated lead-time requirements should reach the Department of State no later than 3 months prior to the start of the research.

  1. Brazil
  2. Canada
