In most instances, foreign investment approval is transparent and simple. However, when a project is evaluated for fiscal concessions, comprehensive documentation is required in order to complete the assessment.

For regulated sectors the BOI forwards the duly completed application form to the relevant authorities who will recommend the approval of foreign investment.

If the project has met the necessary conditions, a Letter of Approval will be issued, which informs the investor of the conditions, privileges and benefits granted. On receiving the Letter of Approval, the applicant must respond, in writing, agreeing to the terms and conditions.
