8 CFR § 1003.38 - Appeals.
(b) The Notice of Appeal to the Board of Immigration Appeals of Decision of Immigration Judge (Form EOIR-26) shall be filed directly with the Board of Immigration Appeals within 30 calendar days after the stating of an Immigration Judge's oral decision or the mailing of an Immigration Judge's written decision. If the final date for filing falls on a Saturday, Sunday, or legal holiday, this appeal time shall be extended to the next business day. A Notice of Appeal (Form EOIR-26) may not be filed by any party who has waived appeal.
(d) A Notice of Appeal (Form EOIR-26) must be accompanied by the appropriate fee or by an Appeal Fee Waiver Request (Form EOIR-26A). If the fee is not paid or the Appeal Fee Waiver Request (Form EOIR-26A) is not filed within the specified time period indicated in paragraph (b) of this section, the appeal will not be deemed properly filed and the decision of the Immigration Judge shall be final to the same extent as though no appeal had been taken.
(e) Within five working days of any change of address, an alien must provide written notice of the change of address on Form EOIR-33 to the Board. Where a party is represented, the representative should also provide to the Board written notice of any change in the representative's business mailing address.
(f) Briefs may be filed by both parties pursuant to 8 CFR 3.3(c).
(g) In any proceeding before the Board wherein the respondent/applicant is represented, the attorney or representative shall file a notice of appearance on the appropriate form. Withdrawal or substitution of an attorney or representative may be permitted by the Board during proceedings only upon written motion submitted without fee.
