Formula Used
Backlog Gap Months = Priority Date minus Visa Bulletin Cutoff Date.
Estimated Backlog Wait = Backlog Gap Months ÷ Bulletin Movement Rate.
USCIS Remaining = Expected USCIS Months minus elapsed months since filing.
Target Estimate = Backlog Wait + USCIS Remaining + NVC Review + Interview Wait.
Low Estimate = Target Estimate × minus buffer.
High Estimate = Target Estimate × plus buffer.

F2B Visa Processing Time Guide
The F2B category is for unmarried sons and daughters of lawful permanent residents. It often moves slowly because annual visa numbers are limited. A good calculator cannot promise an exact approval date. It can organize the main dates and show a practical planning range.
Why Priority Date Matters
Your priority date is usually the date USCIS received the family petition. The visa bulletin cutoff date shows which cases can move forward. When your priority date is earlier than, or equal to, the cutoff date, the case is considered current. Until then, the applicant normally waits in the preference backlog.
How This Tool Helps
This calculator compares your priority date with the latest cutoff date you enter. It then estimates how long the backlog may take, using the monthly movement rate you provide. It also adds USCIS review time, NVC document review time, and expected interview scheduling time. These parts create a low, target, and high estimate.
Use Real Case Data
Better inputs give better estimates. Use your receipt notice for the filing date. Use your approval notice for the approval date. Use the Department of State visa bulletin for the cutoff date. Use consulate information for interview delay. Update the numbers whenever the bulletin changes.
Understand the Limits
Visa timelines can change quickly. Retrogression, country demand, missing documents, age-out questions, or administrative processing can add delay. Marriage can also affect F2B eligibility. This tool is for planning only. It does not replace legal advice, USCIS notices, NVC messages, or official government updates.
Planning Tips
Keep copies of every notice. Track your civil documents early. Watch the visa bulletin monthly. Review passport validity before the case becomes current. Save results from this calculator as a CSV or PDF. Those records can help families compare old assumptions with new movement.
Reading the Result
The target estimate uses your entered movement rate. The low estimate assumes faster progress and shorter handling. The high estimate allows slower movement and extra review. Treat the range as a budgeting and document planning aid. If your date is current, focus on NVC steps, interview readiness, medical exam timing, and updated financial support forms. Check each official notice before making final travel plans.
FAQs
What is an F2B visa?
The F2B category is for unmarried sons and daughters, age 21 or older, of lawful permanent residents. It is a family preference category and usually has a waiting period.
What is a priority date?
The priority date is usually the date USCIS received the I-130 petition. It controls the applicant’s place in the visa waiting line.
What does current mean?
A case is current when the priority date is earlier than, or equal to, the listed visa bulletin cutoff date for that category and chargeability area.
Can this calculator predict the exact interview date?
No. It gives an estimated range. Interview dates depend on visa availability, NVC status, consulate workload, security checks, and document readiness.
What is bulletin movement rate?
It estimates how fast the visa bulletin cutoff date moves. A rate of 1 means the cutoff advances about one month per real month.
Why does the result include USCIS time?
Some users may still wait for I-130 approval. The calculator adds remaining USCIS time when no approval date is entered.
Does marriage affect F2B eligibility?
Yes. F2B is for unmarried sons and daughters of permanent residents. Marriage can change eligibility and should be reviewed carefully.
Should I rely only on this estimate?
No. Always check USCIS notices, NVC messages, and visa bulletin updates. Use this tool for planning, not as legal advice.
