@Ray ****
you could be asked for the landlords i/d and house book OR you might not be. I'd say have it ready in case they ask
And you WILL need a hand drawn map of your neighborhood.
What you gave to get the 90 day Non-O visa has nothing as far as what you will provide to get a yearly extension. Two completely different sections (C-1 for the Non-O and L for the retirement extension, two completely different sets of documentation..
There is no problem going when you have 45 days or less left on your stamp because you won't lose any days going early. They ADD the year to your current expiration date (March 23 2019).
