Date of filing.
Date of filing. A document that is filed with a Board office by personal delivery is considered filed on the date on which the Board office receives it. The date of filing by facsimile is the date of the facsimile. The date of filing by mail is determined by the postmark date; if no legible postmark date appears on the mailing, the submission is presumed to have been mailed five days (excluding days on which the Board is closed for business) before its receipt. The date of filing by commercial delivery is the date the document was delivered to the commercial delivery service. The date of filing by e-filing is the date of electronic submission.
