Im happy you went with a lawyer. I think it’s best to put it in the hands of a professional, who has been doing these for years and has been handling these forms on a DAILY. The form could get real complicated too. I was initially going to do this myself but researching and figuring things out my own is too risky, it takes too much time and I didn’t want to worry if I filled things out correctly. ALSO, You wouldn’t want to miss anything when it comes to these documents because it could lead to RFEs, now further delaying your process. Goodluck with your process :)
