To whom may concern it, Could you please tell me the boundaries or other examples of the professional licenses? According to this page: https://www.synapse.org/#!Synapse:syn11269541/wiki/485634, we have three options for the validation documentation (Step 3, Phase 4). This page says that the third option is "a copy of your professional license" such as medical licenses. But I'd like to know more concretely what are or are not included in the professional license (such as driver license, passport, and so on). Regards
