From Section 3.4 of the Cycle 0 Proposers Guide:
"ALMA proposals may be submitted by investigators of any nationality or affiliation. Each proposal must identify a single individual who will serve as Principal Investigator (PI). ... Successful projects will have their observing time assigned to the region of the PI. The latter is defined as the region to which the organization that employs the PI belongs, or as the region of residence for unaffiliated PIs."
"If a PI has access to ALMA through two regions (e.g. due to a joint appointment at two organizations or as a member of an organization in Taiwan), the PI will have the option to submit proposals affiliated with either of the regions. ALMA proposals may also be submitted by PIs whose affiliation does not lie within any ALMA Executive’s region."
"ALMA policies prohibit the same proposal to be submitted with different Executive affiliations. If such proposals are detected, the first will be considered and the remaining proposals ignored."
By international agreement, ALMA time is shared between the three Executives (NA, EU, and EA) and Chile in the following proportions:
Time for proposals submitted by PIs from outside one of the four ALMA-member regions (EA, EU, NA or Chile) will be shared between the four ALMA regions in the proportions listed above.
