We interpret the observed differences as an effect of English-language skills and construct an instrumental variable for English-language proficiency. Two-stage- least-squares estimates suggest that English proficiency raises the probabilities of marrying a native, being divorced, or having a high-earning and/or more educated spouse, and reduces the number of children.
