New Passport Instructions. Applicants must complete the DS-11 application form. The signature line will need to be left blank until the acceptance agent instructs you to sign it. In this and in all other cases below, two copies of the letter of authorization will then need to be completed by hand and signed in black or blue ink.

You sign it in ink, and print your address (on page 7 of the passport) in pencil, so that if your address changes you can update it. No color of ink is specified, so I suppose any color is OK in theory -- but as a practical matter I'd stick to black or dark blue. You do NOT want your passport raising official eyebrows in foreign countries, do you?
