Yes, you can. There is a procedure whereby the petitioner (the US citizen individual) petitions for the foreign-born Fianc? / Fianc?e to come to the United States. After the Fianc? / Fianc?e is issued a visa, he or she can come to the United States. However, he or she must marry the petitioner within 90 days after entry to the United States otherwise the visa is dead.
