Foreign Tax Credit US RSU

Hi, I moved from US to Canada recently and planning to file T1213 for my US stock vestings and avoid double taxation. I sent these documents to CRA:

1. Stock vestings schedule.
2. T1213 with estimated income and tax.
3. US tax deductions proof of previous vesting schedule.
4. Address proof.

What is the approval rate for the T1213? Does CRA approve for full estimate? And timeline for the process?
