可以上艇。注意你这种情况须由学校的留学生顾问在I-20表后签字。即依据下面规定：

Persons wishing to travel to The Bahamas should possess a valid US multiple entry visa, with the exemption of the following:

• F1 visa holders- students may travel to The Bahamas on an expired F1 visa as long as the Form I-20 is valid. Please note that the authoring officer from the institution attended must sign the back portion of the form. The form is valid for 1 year from the date of the signature.
