It should not have affect on decision. If this affects decision making of officer than this law loses its importance and then it means we are living in the most unjust and unlawful country which I think is not true. Yes, you need a good lawyer to file this request and I think lawyers charge unreasonable amount for this request
yet, I will file it for my application as soon as it hits 18 months of processing times. I WILL NOT tolerate them to sit on my application and do not do any work cause if I do the same at my job I will be fired next day. Plus we are the "customer/clients" since we are the ones paying application processing fees that are part of their salaries....
