For international students wondering if siblings, not just parents, can get visitor visas for convocation:
- Siblings go through the same visitor visa process as any other family member — there's no separate or harder category for siblings specifically.
- Apply together as a family group alongside your parents, rather than submitting the sibling's application separately or later — a joint, well-documented family application (with a clear shared purpose: attending your graduation) tends to read more coherently to a visa officer.
- Members noted approval chances for family visitor visas tied to a student's convocation have generally been favorable recently, though individual circumstances (finances, travel history, home ties) still matter as with any visitor visa.
Treat the sibling's application the same way you would your parents' — same document standards, submitted together, with convocation as the clearly stated purpose of travel.
