For your information, we would be able to issue a dependent I-20 for your new husband to apply for an F-2 visa once we have sufficient documentation (biographical page from his passport and a copy of the marriage certificate). Unfortunately, it’s usually not a wise choice to issue a dependent I-20 prior to the marriage as different consular officials may scrutinize documents more closely. If we were to issue a dependent I-20, we would also have to issue you a new I-20 as well, which may be problematic when you arrive at the port of entry if your current I-20 (which you used to obtain the F-1 visa) is in a sealed envelope.
In addition, it’s generally recommended that students in the F-1 status complete a full semester before they bring their spouse as a dependent. You may want to consider waiting for a minimum of 3 months after marriage to bring a dependent, as this is something that many consular officials check before issuing the F-2 visa. There are many challenges that you will face as a student in your first semester – adjusting to classes and life in the USA is a HUGE change (as is marriage)!!!
Ultimately, the decision to bring your husband is up to you, so please let us know what you would prefer.
