Which abbreviation refers to the practice of sharing information and collaborating within immigration contexts?

The correct abbreviation referring to the practice of sharing information and collaborating within immigration contexts is ISC, which stands for "Immigration Services Collaboration." This emphasizes the importance of communication and partnership across various immigration agencies and sectors to ensure effective and efficient handling of cases.

The other abbreviations listed have different meanings: ISCAP stands for "Information Sharing and Collaboration Program," which is related but specifically focuses on targeted programs rather than the broader context of immigration collaboration. ISDN, or Integrated Services Digital Network, pertains to telecommunications and does not relate to immigration practices. ISOO stands for "Information Security Oversight Office," which deals with government information security rather than immigration matters. Each of these frameworks has specific applications that do not center on the collaborative practices within immigration contexts as ISC does.
