How long does it take for a sibling-sponsored green card to be processed?

For Indian applicants, sibling-sponsored green cards (F4 category) can take 15–18 years due to high backlog.

The wait depends on your priority date and country — it moves slowly each year under the F4 category.

After I-130 approval, the visa bulletin determines availability; processing may vary between 14 to 20+ years.
