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.
If you are in the United States, you can apply for the Green Card with the USCIS. If not, you will have to apply for the same in the Embassy or Consulate in your country of residence. The same will take anywhere between 9 to 12 months. Overall, the investment-based Green Card will take around 15 to 18 months. The document that you will get at the end of this period will be a conditional Green Card. In order to remove these conditions, you will have to file the I-829 petition, but only after 2 years.
