Practice Notes

• Identify the controlling law based on birth/eligibility dates; cite INA sections for acquisition/derivation.
• Ensure physical presence calculations for the USC parent are complete and well-documented.
• For derivation, confirm LPR status and required residence with USC parent before age thresholds.
• Include certified translations; keep originals for interview.
• Consider also filing for a U.S. passport once evidence is compiled.
