How long after my last day can I submit expenses for FSA reimbursement?

I am leaving my current job next week. As of today, I have deposit about $750 into my FSA health account, but only made claims of $460. In order to use the entire $750 do I have to submit claims dated on or prior to my last day or can I use the rest of the year to do that (since its use it or lose it by the end of the year)?|||Check with your human resources department because such a benefit may terminate on your last day. If that is not the case then you can submit claims up to the last day of 2006.
