If you got your ITA and noticed your father's name appears only partially (e.g. first and middle name) on his own passport, while your passport lists his full name (first, middle, and last):
- This generally isn't an issue as long as the father's name on your own passport and documents is consistent across your other supporting documents. Officers are reviewing your file and your documents, not independently verifying your father's passport.
- His passport itself typically isn't cross-checked against your application in this scenario, so a naming discrepancy specific to his own document doesn't usually surface as a problem.
If you want extra reassurance, keeping consistency across your own documents (birth certificate, other IDs) that reference your father's name is more relevant than his passport matching exactly.
