USCIS updated its policy to now adopt a risk-based approach 
When waiving interviews for conditional permanent residents (CPR) who have filed a petition to remove the conditions on their permanent resident status. USCIS officers will be given new criteria on when to waive interviews for CPRs who filed a Form I-751.
Previously, all CPRs were required to be interviewed if they had CPR status via consular processing.
The change to having a risk-based approach will increase efficiencies to improve processing time and make better use of staffing resources. Overall,
This will help reduce the caseload while maintaining procedures to protect national security and detect fraud.
