Can I submit the application on behalf of my elderly parents?

Seniors over 70 can entrust someone to submit application and pick up as they are exempted from fingerprints but people aged 14-70 need to register their fingerprints in person at the Visa Center. You will be responsible to confirm with your mom about the submission and the fingerprint collection. I didn't find there is any form for it. You need to consult the Embasst or consulate-general for your mom's case.
