I begin to worry that the real bottleneck is not at USCIS, but at the IRCC side. They might be not ready to resume the process, including biometrics. Many procedures including but not limited to EE applications have been halted or slowed down due to the pandemic, they may not be able to move forward with most of employees working from home, so they on purpose delayed the biometrics collection to wait until the pandemic recedes. This could explain why so many countries could not resume biometrics even after most of their government has been back to work. Hope this is not true...Same as before, if you are interested in the idea of writing a letter to IRCC and gather hundreds, even thousands of signatures urging them to waive/postpone the biometrics requirement, pls let me know. This may not help much but changes are more likely to happen if we voice out.
