As a general rule, yes. However, the fact that you had your interview and your case was not approved at that time is indicative that there may be an issue with your case and travel may not be wise. Cases which are readily approvable are approved at the interview. Backlogs at a local office are for cases which an examiner has held because he or she is concerned about eligibility (perhaps incorrectly so, but concern nonetheless). I suggest you consult with an experienced immigration attorney before taking any action, especially travel.
