What type of endorsement is needed for workers who travel abroad for work-related activities?

The correct answer is the Foreign Coverage Endorsement because this type of endorsement specifically addresses the needs of workers who are required to travel abroad for work-related activities. It provides the necessary workers' compensation coverage for employees when they are outside of the United States, ensuring that they are protected under their employer's insurance policy while engaged in work-related tasks in foreign countries.

While other endorsements may seem relevant, they do not specifically cater to the unique requirements of workers' compensation for international activities. The International Coverage Endorsement and Global Liability Endorsement may provide broader coverage, but they do not specifically focus on the workers' compensation aspect. The Overseas Workers' Compensation Endorsement might imply a similar aim, but the Foreign Coverage Endorsement is the most precise and commonly used term in the context of workers traveling abroad, making it the best option.
