Your lawyer's advice was based on the current policy, and he assumed that nothing would change in 6 months (Feb 2025). In my opinion, you should file now which you are eligible to file it early based on the current policy. Once your application is accepted into their system, they will not cancel it once or after he is in office. The processing time is likely to take longer than the current pace, which is about 16 months and you should have already met the one-year residency requirement.
The best answer would be to consult your lawyer if you want to file it now instead of waiting until February 2025. You hired a lawyer to help you with the process! Utilize them!
