hi, i am going to apply for study permit on behalf of someone online. the applicant gave me the permission of doing so. i am wondering that should he sign each forms individually? (ie. FAMILY_INFORMATION_IMM5645E, STUDY_PERMIT_APP_IMM1294E, USE_OF_REP_IMM5476E). as well as for the use of representative do i need to sign?. because i watched on youtube saying that ''if you apply for study permit online, you do not need to sign the forms''. your valuable help is appreciated!
