However, certain US laws can still apply to US citizens or US companies abroad, including when they are in Greenland.

Why US law does not apply territorially
Territorial application of law depends on sovereignty. Greenland is not a US territory or state and is therefore not governed by US federal or state law.
Greenland is part of the Kingdom of Denmark, and its legal system is based on Greenlandic and Danish law, not US law.
Which law applies in Greenland
In everyday life, the laws that apply in Greenland are:
- Greenlandic law for most domestic matters
- Danish law in areas that remain under Denmark’s authority
This includes criminal law, civil law, labor rules, property law, and local regulations.
US law does not replace or override these legal systems.
When US law can apply to Americans
Some US laws follow US citizens regardless of where they live. This is not unique to Greenland.
Examples include:
- US tax obligations for US citizens and permanent residents
- Certain federal criminal laws with extraterritorial reach
- Reporting obligations related to foreign accounts or businesses
These laws apply because of a person’s connection to the United States, not because Greenland is under US jurisdiction.
US companies and US law
US companies operating or investing in Greenland must comply with:
- Greenlandic and Danish law for local operations
- Relevant US laws that apply extraterritorially
This can include sanctions rules, export controls, and anti-corruption laws.
Operating abroad does not remove US legal obligations, but it also does not turn Greenland into US jurisdiction.
Common points of confusion
- Military presence: US bases operate under agreements, not US sovereignty.
- US citizens abroad: Personal obligations do not equal territorial law.
- Headlines: Media language often simplifies complex legal realities.
A useful rule of thumb: where you are physically located determines territorial law, while citizenship can determine personal obligations.
