Many Dominicans, especially in the urban areas, have at least the equivalent of a high school education.
While Spanish is the official language of the Dominican Republic, English is taught as a second language in most religious and private schools. Broadband internet access is available throughout most of the country - making it very easy to maintain a long distance relationship.
Although mostly Christian, it has a long history of religious freedom, and contains communities from many religious faiths such as Judaism, Islam, Buddhism, Baha'i... Even more surprisingly, over 10% of Dominicans claim no religion at all-either agnostic, atheist, or religious but non-practicing.
Finally, the Dominican Republic has had a stable democracy since 1978.
Although many girls from the Dominican Republic may not be fluent and will almost certainly have an accent, they should be able to communicate in English and will quickly improve their linguistic skills once they marry and move to an English-speaking country where they are immersed in the language around them. Over 83% of Dominicans have mobile phones, and many internet service providers offer wireless 3G internet for laptops and smart phones.
