We present a detailed description of the special procedures for calibrationand quality assurance of Atacama Large Millimeter/submillimeter Array (ALMA)observations in Very Long Baseline Interferometry (VLBI) mode. These proceduresare required to turn the phased ALMA array into a fully calibrated VLBIstation. As an illustration of these methodologies, we presentfull-polarization observations carried out with ALMA as a phased array at 3mm(Band 3) and 1.3mm (Band 6) as part of Cycle-4. These are the first VLBIscience observations conducted with ALMA and were obtained during a 2017 VLBIcampaign in concert with other telescopes worldwide as part of the Globalmm-VLBI Array (GMVA, April 1-3) and the Event Horizon Telescope (EHT, April5-11) in ALMA Bands 3 and 6, respectively.
