I agree. I am overthinking this. Overworrying this. Overdoing this. If I get the documents from decades ago somehow to please the USCIS, or if the USCIS would return to me the very documents they are asking me for (what a joke!) in time, i.e. in 60 days, I should be alright. I am putting time, effort, and money (attorney) into this.
Thank you for support and help.
I am pretty sure: when people read through difficult cases, which mine is for sure, they can learn something for themselves. I wish it could be easier for us.
