This crucial first step involves figuring out if you’re applying for a new passport (using form DS-11) or renewing an old one (using form DS-82). You’ll need a new passport if you’ve never had one, if your previous one was issued before you turned 16, if it’s been lost or stolen, or if it expired more than 15 years ago. Renewals apply to passports issued when you were 16 or older, less than 15 years ago, and are still in good condition. For minor applications, both parents generally need to be present with their ID, along with the child and their birth certificate. Understanding this distinction early on saves a lot of headaches, ensuring you complete the correct paperwork right from the start.

Next, gather your irrefutable proof of U.S. citizenship and a valid form of identification. For citizenship, this usually means your original birth certificate (not a copy!), a previous undamaged passport, or a Certificate of Naturalization. Remember, you’ll likely need the *original* or a certified copy with a raised seal. For ID, your valid Colorado driver’s license or state ID card is perfect. Make sure it’s current and hasn’t expired. You’ll need both the original and a photocopy of the front and back of your ID. For Thornton residents, double-check your documents well in advance of any appointment to avoid last-minute scrambles and ensure everything is up to date.

Now it’s time to accurately fill out the correct passport application form. If you determined you need a new passport or are applying for a minor, that’s the DS-11. For renewals, grab the DS-82. You can access these forms online at the U.S. Department of State website (travel.state.gov) and print them out. *Do not sign* the DS-11 form until you are in front of a passport acceptance agent! Fill in all sections clearly and truthfully. Mistakes or omissions can delay your application significantly. Take your time, read all instructions carefully, and ensure every detail matches your supporting documents precisely.

Your passport photo has strict requirements, so don’t just use any selfie! It needs to be a recent (taken within the last six months) color photo, 2×2 inches, with a white or off-white background. You must have a neutral facial expression or a slight, natural smile, with both eyes open. No glasses are allowed unless medically necessary, and head coverings are only permitted for religious reasons with a signed statement. For Thornton residents, numerous places offer passport photo services, including most Walgreens, CVS pharmacies, or The UPS Store locations around the city. They typically know the specific requirements and can get it right the first time.

Understanding the costs involved is crucial. There are two main fees: the passport application fee and the execution fee. The application fee (for the passport itself) must be paid directly to the U.S. Department of State via check or money order. *They do not accept credit cards for this fee.* The separate execution fee (paid to the acceptance facility for processing your application) can often be paid by check, money order, or sometimes credit card, depending on the facility. Always confirm the current fees on travel.state.gov and the accepted payment methods with your chosen Thornton acceptance facility before your visit. Having everything ready prevents delays.

Finally, it’s time to submit your completed application. This requires an in-person visit if you’re applying for a new passport (DS-11) or for a minor. For renewals (DS-82), you’ll mail it in yourself. For in-person applications, seek out a passport acceptance facility. In Thornton, your local USPS branches often serve this purpose, or sometimes city/county clerk offices. For example, the USPS at 8820 Huron St, Thornton, CO 80221, is a common spot. Always call ahead or check their website to confirm hours, required appointments, and their specific payment methods for the execution fee. Bring all your original documents, photocopies, completed forms, photo, and payment.
