The admissions process can take several months depending on various factors. It is the applicant’s responsibility to ensure that all appropriate materials are forwarded to the appropriate department.
Once you submit your application you should continue to monitor your application checklist for any requested items. You can find your checklist: https://admissions.ufl.edu/appstatus.
For international students, it is very common for the international admissions team to request additional documentation. Almost all of the additional requested materials can be uploaded via your online application using the unofficial transcripts tab (even if the item being uploaded is not an actual transcript).
