Based on my experience and conversation with a person that personally knows our MP, it is not going to do anything. You will get some answer from MP, but it will be the same you get on the phone with IRCC. MP will be like, "it is very important, good bye". As one person mentioned here (and I absolutely agree), the only thing that works is calling them in the morning and be very polite and professional, and do not talk about time line, that it takes too long or how you stressed. Operator should say that. It looks like we all have some rating based on how we do the paperwork and communicate.
