Once your fiancè(e) enters the U.S., marriage must occur within 90 days of his/her arrival. Unfortunately, you may encounter hardship enrolling your fiancè(e) into your domestic health insurance plan (mostly provided to you by your employer), until marriage and in most cases for a certain duration after marriage.
As a newly arrived person in the U.S., your fiancè(e) would not be immediately eligible for regular domestic health insurance. The majority of companies require the person to be a resident of the U.S. for 6 months, 12 months or 2 years at the most. Many companies also require that the person either be a U.S. citizen or lawful permanent resident; your fiancè(e) would not satisfy these requirements. Moreover, even an eligible person can only enroll into regular domestic health insurance during an open enrollment period (typically Nov. 1 to Dec. 15 ) and not at any time throughout the year unless they qualify for a special enrollment period.
As an interim solution, we have excellent insurance products available exactly for the person just like your fiancè(e).
