The temporary visa category created for Mexican and Canadian NAFTA Professional Workers enabled 92,951 Canadians and 2,571 Mexicans to enter the United States on visas in 2001.

The refractive index of the suspected glass can be known by using the backe- line method. This process takes place in a petrographic microscope. In this method an oil comparable to the refractive index of the glass is used.

This method can be used to identify the refractive index of the suspect glass and comparing it with the source of origin or sample glass.
