Final answer:
No new sponsor entry is required in the UAC portal for an address update; the existing sponsor profile should be edited to ensure data integrity.
Step-by-step explanation:
When updating a sponsor's information in the UAC portal, it is not necessary to create a new sponsor entry. Instead, the Case Manager (CM) should locate the existing sponsor profile and update the contact information with the new address.
This ensures that all information regarding the sponsor is kept in a single record, thereby maintaining data integrity and facilitating effective case management. Records in such databases are typically designed to be updated so that historical relationships and data can be preserved.
