Like I said in my comment you dont have to respond if you cannot meet up the unreasonable request made by the IRCC. Just wait for 30 days and they will go back to attending to your application as per normal.Not all nigeria big banks are partner to visa-mybankstatement.com. First Bank is not a partner and ircc is again requesting from me to submit my bank statement using this method. I applied without NSE and am surprise when 2 weeks deadline was given to submit my bank statement through this means and Ielts. I used First Bank and the bank statement sent to them when I applied was from First Bank. There is no way I could meet 6-12 months duration of bank statement even if I choose to use any other bank listed on visa-mybankstatement.com. 30 days is given to send it. Should I explain this to them?
What they are doing is wrong. The SDS program they do for Asian students has a different application portal dedicated to SDS (student direct stream) applications. So if an applicant wants regular application they go through the normal process and follow the rules there, if they want the SDS route they apply through that ans follow the applicable rules. But they a Nigerian applicant should not apply for the regular process and in the middle of the application request for another route and change the rules. That is unprofessional. If they want to set up the express student entry for Nigerians, a different portal should be set up when applicants interested in that route go there, apply and follow the prevailing rules there.
All the best.
