100 Dumb US Laws (With Proof They Exist)
For travel to the U.S. for tourism or business purposes with a stay of up to 90 days, a valid passport and an approved ESTA travel registration are usually sufficient. This applies to citizens of countries included in the U.S. Visa Waiver Program, such as the United Kingdom and Ireland. There is no need to visit an embassy or attend an interview. This article is designed to assist individuals who need to apply for a non-immigrant visa to the U.S. or wish to do so for any reason, including cases where their ESTA application has been denied.

1️⃣ Dimensions
For digital uploads, the photo must be square, between 600×600 and 1,200×1,200 pixels. If you bring a physical photo, it must be 2 × 2 inches (51 × 51 mm).
2️⃣ Color
The photo must be in color (sRGB color space preferred for digital). Black and white photos are not accepted.
3️⃣ File Format
Only the JPEG (.jpg) format is accepted for digital uploads.
4️⃣ File Size
The file size must be less than or equal to 240 kB. Compression ratio should be less than or equal to 20:1.
5️⃣ Photo Content
The photograph must show the entire face, neck, and shoulders facing the camera. The expression must be neutral, with both eyes open. Do not smile. The head must be centered and not tilted. The head height (top of hair to bottom of chin) should measure 50% to 69% of the image’s total height. The background must be plain white or off-white and free of shadows.
6️⃣ Technical Requirements
The entire face must be in focus. Brightness and contrast must be balanced. There should be no shadows on the face or background.
7️⃣ Glasses and Accessories
Glasses are not allowed in U.S. visa photos. You must remove them. The only exception is if they cannot be removed for medical reasons (e.g., the applicant has recently had ocular surgery and the glasses are necessary to protect the applicant’s eyes). In such cases, a medical statement signed by a medical professional/health practitioner must be provided. Hats and head coverings are only permitted for religious purposes and must not obscure any part of the face.
You can verify your photo using the official photo tool.

Frequently Asked Questions About Visas to the USA
I already have a visa for the U.S., but my passport will expire soon. What is the minimum required validity period for my passport?
For the UK, Ireland, and other members of the Six-Month Club, your passport only needs to be valid for the duration of your stay. You do not need an additional 6 months of validity beyond your departure date.Can I apply for a U.S. visa in another country, or do I always have to apply in the UK?
It is strongly recommended to apply for a visa in your country of permanent residence (e.g., the UK). While you can technically apply at any U.S. consulate worldwide as a “Third Country National,” it is riskier. Officers may find it difficult to evaluate your ties to your home country, increasing the chance of denial.Can I apply for a U.S. visa if I have a criminal record?
Yes, you can apply, but you must disclose your arrest or conviction on the DS-160 form and bring all relevant court documents (ACRO Police Certificate for UK applicants) to the interview. This applies even if the offense is considered “spent” under UK law.Who must attend the visa interview in person?
Generally, applicants between the ages of 14 and 79 must attend the interview. Children under 14 usually do not need to appear if their parents are applying, but regulations can vary, so check the specific instructions on your appointment confirmation. Applicants aged 80 and over are typically exempt from the interview.How much money do I need in my bank account to get a U.S. visa?
There is no fixed minimum amount required by law. However, you must demonstrate that you have sufficient funds to cover your travel, accommodation, and living expenses for the entire duration of your trip without seeking unauthorized employment.Will the fee for a U.S. visa be refunded if the visa is denied?
No. The fee is a processing fee for the application, not for the issuance of the visa. It is non-refundable regardless of the outcome.How long does it take to process a U.S. visa?
Processing times vary significantly based on demand. While the interview itself is short, waiting for an available appointment slot can take weeks or even months. After approval at the interview, the passport with the visa is typically returned via courier within 3 to 10 business days.

Hi, do I need to apply for an ESTA if I already have a valid visitor visa?
@Helen: Hello Helen,
No. :-)
If you already hold a valid B1/B2 visitor visa, you do not need to apply for ESTA. ESTA is required only for travelers who choose to enter under the Visa Waiver Program without a visa. Simply travel on your visa, ensure your trip purpose and duration match the visa class, and carry the passport that contains the visa.
If the visa is in an old passport, carry both old and new passports. Having an approved ESTA is irrelevant if you are entering on your visa, and as always, final admission is decided by CBP at the port of entry. :-)
