Foreign diplomats and ambassadors enjoy diplomatic immunity, which means they are not subject to the laws and jurisdiction of the host country in which they are serving. This immunity extends to both criminal and civil laws, which means they cannot be sued or prosecuted in the host country. As a result, foreign diplomats and ambassadors generally cannot enter into contracts in their personal capacity. However, they may enter into contracts on behalf of their home country or their embassy, in accordance with international law and their own country's laws and regulations. Foreign diplomats and ambassadors have the right to free movement and travel within the host country, and they are exempt from certain taxes and customs duties. They are also entitled to certain privileges and immunities, such as exemption from arrest and detention, inviolability of their residence and communication, and immunity from civil and administrative jurisdiction. At the same time, foreign diplomats and ambassadors also have certain obligations and responsibilities. They are expected to respect the laws and regulations of the host country, and to refrain from interfering in the internal affairs of the host country. They must also abide by the rules and customs of diplomatic protocol, and maintain good relations with the host government and local community. If they violate any of these obligations or responsibilities, they may face disciplinary action or be expelled from the host country.
