Do i have to apply for OPT(f1 status) even i file for i765 through my husband who is a citizen?

It is up to you as to whether you wish to maintain F-1 status or just go through your husband's petition with the attendant I 765 employment authorization. The favorable factor of keeping F-1 status is that you may be able to use it as a backup in the event that anything goes wrong with your marriage case. Without it, you would be wholly dependent on your adjustment of status application to keep you legally in the country.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.
