可以上艇。注意你這種情況須由學校的留學生顧問在I-20表後簽字。即依據下麵規定：

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.
