Oh wow... yeah.., no one in their right mind would hope to get approved after 800 days of absence. Not sure if any such instances are there but your words give me much hope for my situation. I deeply appreciate it but you know anything concerning immigration is always stressful cuz regardless of what rules and conditions their website says.., in reality they have a mind of their own and its very unpredictable... in my experience.. one should not expect that CBP at the POE will entertain anything unless there is any documentaional proof.. and yeah not having any definate set of days that you can stay out of the US without worring about losing your LPR status is worrisome all the way...
