What is the US visa application process?
Applying for a U.S. visa can feel confusing at first. There are forms, interviews, and different rules depending on where you’re from and why you’re going.
Step 1. Check If You Need a Visa
Not all travelers need a visa to visit the U.S. People from Visa Waiver Program countries can visit the US for tourism or business for up to 90 days; even without a visa. No VWP? You must apply for a visa.
Step 2: Choose the Correct Visa Type
The US offers tourist/business, student, skilled worker, and fiancé(e) visas. Choosing the right visa is important. If you choose the wrong one, your application could be delayed or denied.
Step 3: Complete Form DS-160
Once you know your visa type, the first big step is filling out a form called DS-160. It asks for your personal info, travel plans, and background. You fill it out online. When you’re done, you’ll get a page with a barcode. Print that for your interview.
Step 4: Pay the Application Fee
Visa fees vary by visa type:
- Non-petition-based visas: $185
- Petition-based (H, L, O, P, Q, R): $205
- E-1, E-2, E-3 visas: $315
In some cases, applicants may also need to pay a reciprocity (issuance) fee, which depends on U.S. diplomatic agreements with their home country. These fees are non-refundable at all times.
Step 5: Schedule a Visa Interview
All applicants between ages 14 and 79 must attend a US visa interview at the U.S. embassy or consulate in their country. After submitting DS-160 and paying the fees, schedule your appointment. You will get an appointment confirmation letter, which must be presented on the day of the interview.
Step 6: Gather Supporting Documents
Prepare a complete document file, including:
- Valid passport
- DS-160 confirmation page
- Visa appointment confirmation
- Visa fee receipt
- One passport-size photo (meeting U.S. photo standards)
- Additional documents based on visa type (e.g., I-20 for F1 students, a job offer for H1B, etc.)
Step 7: Attend the Visa Interview
Go to the US embassy or consulate on time. A US consular officer will review your documents and ask questions related to your travel intent, financial stability, and ties to your home country. The officer will tell you if your case needs additional administrative processing.
Step 8: Wait for Processing
Visa processing times range from a few days to several weeks. It depends on your visa category, your nationality, and the specific embassy’s workload. Do not make travel arrangements until your visa has been approved and issued. You’ll be notified by the embassy or consulate when your passport with visa is ready for pickup or delivery.
What is the difference between US immigrant and non-immigrant visas?
Types of US visas fall into two categories:
- Immigrant
- Non-immigrant.
The main difference between US immigrant and non-immigrant visas is the length of stay. Nonimmigrant US visas are temporary visas, and after expiration, the holder must return to his or her home country immediately.
Immigrant visas or US Green Cards do not need to be renewed and are permanent. Holders of these visas can live and work in the United States as long as they wish.
How to Check the Status of Your U.S. Visa Application?
To check the progress, you’ll need your case number or application ID. You should have received this during your application or at the interview. Go to the official visa status check website and type in your case number carefully. Make sure everything is correct.
Once submitted, the system will show your current status. You might see something like “Administrative Processing,” “Issued,” or “Refused.” Don’t panic if you don’t fully understand what it says. Some statuses just mean your case needs a little more time. Many people see “Administrative Processing” for a few days or weeks before getting approved. It’s completely normal.
If it’s been several weeks and you’re still not sure what’s happening, you can contact the U.S. embassy or consulate where you applied. Have your case number ready when you reach out. They may be able to give you more information or let you know if they need anything else from you.
How to renew a US visa?
If your visa expires, you can renew it. The US visa renewal process is similar to the visa application process. The date of issuance and expiration of US visas will be stamped on your passport. The application process for a US visa extension is done in two steps:
First step. Make payments
You need to make all necessary payments depending on your visa type. Further processing will not be done if you do not pay the fees.
Second step. Complete online application form
The online application form DS-160 must be filled out. When the form is completed, a confirmation page and a number will appear that you must save.
Third step. Submit the documents
You must provide all the requirements.
Fourth step. Visa interview
You have to schedule an interview appointment and attend it.
Can US visa holders bring their spouses, children, and parents to the United States?
All US visas allow you to bring your spouse and unmarried children under the age of 18 or 21.
Most US visas do not allow you to bring your parents to this country except holders of Immediate Relative or Family-Based Immigrant Visas visas. For more information on the terms of these visas, read, “All you need to know about the US family-based visa program” article which you can visit from the left sidebar.
How do I get US citizenship?

You must first change your nonimmigrant visa to an immigrant visa. Some US nonimmigrant visas, such as the H1B, are dual intent. This means that you can change the status of your visa to an immigrant visa. You can apply for US citizenship five years after receiving your US immigration visa.

How to travel to the US under a visa waiver program?
People going to the United States as part of a visa waiver program do not need a travel visa but must obtain an Electronic System for Travel Authorization (ESTA). These people also need an e-passport. The e-passport is slightly different from the regular passport and has an electronic chip, and is machine-readable. Overall, the experience of traveling under the US Visa Waiver Program can be very pleasant.
