U.S. Citizenship and Immigration Services is changing the look of its receipt and approval notices (form I-797C). These forms do not carry any immigration benefit or status. As such, they will now be printed on plain bond paper to reduce the perception that they signify a change in immigration status. In addition, by changing to bond paper, USCIS has estimated that it will save $1.1 million per year.
The change went into effect on Monday April 2, 2012.
