The way that I read his last paragraph in the original post made it sound like that......"It is a good idea to make sure that when you use any of the aforementioned forms that you use the new ones as using the old ones may cause a delay or rejection when you do any business with the National Immigration Institute or INAMI. It is unknown when immigration / airports / border crossings will have the new forms available as well as if there will be any grace period for use of old forms"
I just wanted to make sure that I had the correct information from Spencer himself. I hope that's alright with you RVGRINGO.
