For Restoration, did you pay any fees? & 200?
I didn't really under that what's the different between restoration vs visa extension?
Applying for restoration is when you applied for extension after your status has expired OR when your application for extension was refused. It's a one time 90-day period. What happened with mine is we initially applied for Spousal Sponsorship + OWP before my status expired. When our application was returned, I lost my implied status and I only had a couple of weeks left to restore it.
