Completing and Filing the I-129

In general, complete all blanks with the information requested or with either "N/A" or "none," as appropriate, trying as best you can not to confuse the two. "N/A" should be used where the concept at issue simply has no bearing on your matter, such as an "A number" for a nonimmigrant, while "none" should be used, for instance, in response to a request for a middle initial. Legible print is OK, typed forms are better. A number of commercial computerized forms programs are available. USCIS will issue a denial (not an RFE, and not merely returning the petition) if it suspects a signature is not original, so be sure to use blue ink or some method that can best convey visually that the signature is original and not the result of a stamp, auto-pen, or other type of device.
