For the second time i submitted a webform explaining my parents situation and asking for extended time. Again i got a vague answer that "you should provide your biometric as soon as possible".
Did anyone get a clear answer on a due date extension request?
How long after the given date is still acceptable for providing the biometric? 30 days, 60 days,etc???
I asked for extension of biometric timeline. I got proper reply that thanks for letting us know your situation and making reasonable efforts to appear for biometric. They also informed USCIS about my request.
I guess, they allowed me extention because, i mentioned reason for not able to give biometric was to not availability of passport on hand and next available appointment was well beyond timeline given to me. So in my case they did. I am guessing that, they can see our appointment booked with USCIS using our IRCC number.
