I'm confused about the electronic signature for online application IMM5257. Me and my wife are applying for supervisa . We each have our own separate application formsIMM5257. They say on the instructions to sign the application form using electronic signature. But there is only the option for one signature. I'm representing me and my wife . But shouldn't we both be signing our own application forms ? should I print out my wife's application formIMM5257 and have her sign manually and then upload it and sign my application form electronically ? Please help ! Thanks !
