As a foreigner, you won’t be granted rights of citizenship in Kuwait. Your only route to becoming a naturalized citizen is by marriage to a national; even this, however, doesn’t guarantee citizenship, particularly for non-Muslims.
In exceptional circumstances only, a Kuwait’s ruler might grant citizenship to a foreigner who has provided outstanding service to the state over a number of years. A generous employer might reward a loyal worker who has made a major contribution to the company over many years by providing him with a work and residence permit of indefinite duration.
Also children of foreigners born in Kuwait don’t have rights of local citizenship and automatically assume the nationality of the parents.
Best!
