Arabic is the official language in over 25 states, including Egypt, Morocco, and Saudi Arabia. The United Nations is also among the international organizations that recognize it. It's an Afroasiatic language introduced in the early centuries. Now, the Arab world uses it as its lingua franca or bridge language.
Because Arabic is in demand, government agencies (such as the United States administration) seek proficient speakers of the language. Proficiency in the language, therefore, can help a person land a promising career in government. And with millions of speakers worldwide, it can provide assistance in business, tourism, and international affairs.
