A Green Card holder who is not a minor can file Form N-400, Application for Naturalization, to obtain US citizenship. Similarly, he must have become a permanent resident before five years and must have remained as a permanent resident in America for at least five long years.
You're going to get a LOT of responses for this. As far as I know and have read (and experienced first-hand), chalk paint is. any kind of paint that has an additive mixed into it to give it a gritty, matte finish and easy drying time. Many people use it because many times it negates the need for sanding a apiece and the finish allows for an easy time if you want to distress the wood.
No. It is similar only in that it is in the form of a dry stick. Chalk is composed of calcium carbonate mixed with silt and clay. It is white or generally light in color and much harder than pastel. Some chalk may, however, be used together with pigment to create paler tints of pastel.
