They routinely tell everyone to show up, whether or not they have ANY idea if a decision will be made, written, reviewed, revised and ready to hand over to you at that time. IF they are not ready with a decision, they just invoke discretionary authority to send it by mail. They give you every opportunity to do the wrong thnig (like not showing up) so they can stop the 180 day clock on issuing an EAD. It is complex but, try to follow the regulations as they cross reference each other.
8 CFR § 208.19 Decisions.
The decision of an asylum officer to grant or to deny asylum or to refer an asylum application, in accordance with §208.14(b) or (c), shall be communicated in writing to the applicant. Pursuant to §208.9(d), an applicant must appear in person to receive and to acknowledge receipt of the decision to grant or deny asylum, or to refer an asylum application unless, in the discretion of the asylum office director, service by mail is appropriate. A letter communicating denial of asylum or referral of the application shall state the basis for denial or referral and include an assessment of the applicant's credibility.
8 CFR § 208.14 Approval, denial, referral, or dismissal of application.
(b) Approval by an asylum officer. In any case within the jurisdiction of the Office of International Affairs, unless otherwise prohibited in §208.13(c), an asylum officer may grant, in the exercise of his or her discretion, asylum to an applicant who qualifies as a refugee under section 101(a)(42) of the Act, and whose identity has been checked pursuant to section 208(d)(5)(A)(i) of the Act.
(c) Denial, referral, or dismissal by an asylum officer. If the asylum officer does not grant asylum to an applicant after an interview conducted in accordance with §208.9, or if, as provided in §208.10, the applicant is deemed to have waived his or her right to an interview or an adjudication by an asylum officer, the asylum officer shall deny, refer, or dismiss the application, as follows:

8 CFR § 208.9 Procedure for interview before an asylum officer.
(d) Upon completion of the interview, the applicant or the applicant's representative shall have an opportunity to make a statement or comment on the evidence presented. The asylum officer may, in his or her discretion, limit the length of such statement or comment and may require its submission in writing. Upon completion of the interview, the applicant shall be informed that he or she must appear in person to receive and to acknowledge receipt of the decision of the asylum officer and any other accompanying material at a time and place designated by the asylum officer, except as otherwise provided by the asylum officer. An applicant's failure to appear to receive and acknowledge receipt of the decision shall be treated as delay caused by the applicant for purposes of §208.7(a)(3) and shall extend the period within which the applicant may not apply for employment authorization by the number of days until the applicant does appear to receive and acknowledge receipt of the decision or until the applicant appears before an immigration judge in response to the issuance of a charging document under §208.14(c).
8 CFR § 208.7 Employment authorization.
(a) Application and approval. (1) Subject to the restrictions contained in sections 208(d) and 236(a) of the Act, an applicant for asylum who is not an aggravated felon shall be eligible pursuant to §§274a.12(c)(8) and 274a.13(a) of this chapter to submit a Form I–765, Application for Employment Authorization. Except in the case of an alien whose asylum application has been recommended for approval, or in the case of an alien who filed an asylum application prior to January 4, 1995, the application shall be submitted no earlier than 150 days after the date on which a complete asylum application submitted in accordance with §§208.3 and 208.4 has been received. In the case of an applicant whose asylum application has been recommended for approval, the applicant may apply for employment authorization when he or she receives notice of the recommended approval. If an asylum application has been returned as incomplete in accordance with §208.3(c)(3), the 150-day period will commence upon receipt by the Service of a complete asylum application. An applicant whose asylum application has been denied by an asylum officer or by an immigration judge within the 150-day period shall not be eligible to apply for employment authorization. If an asylum application is denied prior to a decision on the application for employment authorization, the application for employment authorization shall be denied. If the asylum application is not so denied, the Service shall have 30 days from the date of filing of the Form I–765 to grant or deny that application, except that no employment authorization shall be issued to an asylum applicant prior to the expiration of the 180-day period following the filing of the asylum application filed on or after April 1, 1997.
(2) The time periods within which the alien may not apply for employment authorization and within which the Service must respond to any such application and within which the asylum application must be adjudicated pursuant to section 208(d)(5)(A)(iii) of the Act shall begin when the alien has filed a complete asylum application in accordance with §§208.3 and 208.4. Any delay requested or caused by the applicant shall not be counted as part of these time periods, including delays caused by failure without good cause to follow the requirements for fingerprint processing. Such time periods shall also be extended by the equivalent of the time between issuance of a request for evidence pursuant to §103.2(b)(8) of this chapter and the receipt of the applicant's response to such request.
(3) The provisions of paragraphs (a)(1) and (a)(2) of this section apply to applications for asylum filed on or after January 4, 1995.
