Flour is the primary ingredient of any bread recipe. It is the bread that we see. Flour contains gluten, a protein that provides for the elasticity, and the basic structure of bread. As the mixture is heated, the starch in bread sets, and adds to the structure.
If you are a U.S. permanent or conditional resident -- that is, someone with a green card -- the basic rule is that you cannot apply for U.S. citizenship (or apply to naturalize) until you have lived in the United States as a lawful permanent resident for at least five years.
Your employer can apply for a green card for you, if they want to. They have to want to keep you very, very badly in order to do this. It will take about a minimum f 6 years from when they apply for you to get a green card. Then, 5 years after you get a green card you can apply for citizenship. You cannot apply for a green card, your employer has to get you one. Don't count on any employer sponsoring you for a green card until you have worked for them at least 3 years. 15 years.
