If the alien desires to make multiple entries and the consular officer or other State Department official believes that the circumstances justify the issuance of a visa valid for multiple entries rather than for a specified number of entries, and recommends that the alien be accorded an authorization valid for multiple entries, the information required by items (ii) and (iii) shall be furnished only with respect to the initial entry. Item (ii) does not apply to a bona fide crewman. The consular officer or other State Department official shall be notified of the decision on his recommendation. No appeal by the alien shall lie from an adverse decision made by a Service officer on the recommendation of a consular officer or other State Department official.
