You should allow up to three weeks for your new passport to be delivered to you.
If you need to travel sooner, please discuss this with your interviewing officer during your interview. Please also bring evidence of your urgent need to travel - e.g. letter from employer, tickets, etc. You may be eligible for an Emergency Passport that can be issued within two working days. An Emergency Passport contains only four visa pages and has a limited validity. It does not contain a chip.
Please note that not all applicants are eligible for an Emergency Passport. You should discuss your eligibility for the Emergency Passport at your interview before making any firm travel plans.
If you are issued with an Emergency Passport it is your responsibility to check whether it will be accepted for entry in the country where you are travelling and whether visas are required. You can enter the United States with an Emergency Passport but you must have a valid visa. You are not eligible for the US Visa Waiver Program (ESTA) with an Emergency Passport.
