Contact the Tampa office directly to find out how it processes K-3-based adjustment applications. Each office treats them slightly differently. Ideally you should be able to file your adjustment application right away, either with a new I-130 or by having the I-130 that is currently pending with the Texas Service Center transferred to the Tampa office.
To schedule an appointment for the Tampa office, use the Infopass service available on that office’s website at:
