Can i change preference category 2B for alien relative petition approved to fiance visa petition?

You are allowed to apply for a fiancée visa instead of sticking with your father's F-2B preference visa which will take a long time for a visa number. I do note that once you have married, the F-2B petition is automatically revoked. If at some point you are divorced, you could not restart the F-2B petition. If you wish to go down that route again, your father would have to put in another petition with a new priority date.Due to the limitations of the Lawyers.com Forums, Alan Lee, Esq.'s (the "Firm") participation in responding to questions posted herein does not constitute legal advice, nor legal representation of the person or entity posting a question.
