How To Smoothly Pass Through Customs When Entering the US
ISO Customer Care | Jul 30, 2026 Student Life
As an international student entering the US, going through immigration and customs can feel stressful. Unfamiliar procedures, possible language barriers, and the pressure to have the right documents ready can create anxiety, even for experienced travelers. With a little preparation, you can approach the process with greater confidence and begin your US journey on a positive note.
Before You Travel
- Gather your documents: Keep your valid passport, F-1 visa, signed Form I-20, SEVIS fee receipt, school admission or enrollment information, proof of financial support, and any relevant academic or employment documents together in your carry-on bag.
- Check your Form I-20: Make sure the information is accurate. Returning students should also confirm that their travel signature is still valid before traveling.
- Do not pack important documents in checked luggage: Keep all immigration and school documents somewhere you can easily access during inspection.
- Review restricted and prohibited items: Visit the US Customs and Border Protection website before packing to review current rules for food, plants, medication, agricultural products, and other restricted items.
- Prepare to declare your belongings: Travelers may need to declare food, medication, purchases, gifts, alcohol, tobacco, and currency or monetary instruments totaling more than $10,000.
What to Expect After Arrival
Although the entire arrival process is often called “going through customs,” international travelers generally complete both an immigration inspection and a customs declaration process.
- Follow airport and CBP instructions: Arrival procedures and processing lines vary by airport. Follow the signs and directions provided by airport and US Customs and Border Protection staff.
- Have your documents ready: Keep your passport, visa, Form I-20, and supporting documents organized and readily available for inspection.
- Be prepared for questions: A CBP officer may ask about your school, academic program, living arrangements, financial support, intended stay, and the items you are bringing into the country.
- Answer honestly and clearly: Keep your answers direct and relevant. If you do not understand a question, politely ask the officer to repeat or clarify it.
- Declare items accurately: When asked about food, medication, purchases, gifts, or other goods, answer accurately and provide additional information when requested.
- Stay calm and respectful: Be polite and cooperative throughout the inspection process, even if you encounter delays or a language barrier.
Tips for a Smoother Experience
- Dress appropriately: Choose comfortable, presentable clothing that allows you to move easily through the airport and access your documents.
- Pack efficiently: Avoid excessive luggage or disorganized bags that may make it difficult to locate an item during inspection.
- Stay organized: Keep all travel documents, identification, and school information in a designated folder or travel pouch.
- Plan ahead: Immigration and customs processing times can vary, especially during peak travel periods. Leave enough time between connecting flights.
- Be mindful of your body language: Try to avoid excessive fidgeting or appearing distracted. Maintain appropriate eye contact, listen carefully, and speak clearly when questioned.
- Ask for clarification when needed: If you are unsure what an officer is asking, politely request that the question be repeated or explained.
Additional Tips for Returning F-1 Students
- Check your passport and visa: Confirm that both documents are valid before traveling.
- Review your Form I-20: Make sure the information is correct and that your travel signature is valid.
- Confirm your SEVIS record: Contact your school’s international student office if you are unsure whether your record remains active.
- Bring supporting documents: Students on OPT or STEM OPT should carry relevant employment authorization and employment information.
After You Enter the US
Your Form I-94 is generally created electronically after you are admitted to the US. After arrival, retrieve your electronic I-94 and review your name, immigration category, and admission information for accuracy.
If any information appears incorrect, contact your school’s international student office as soon as possible.
Traveling With Your ISO Insurance Information
It is helpful to keep your ISO insurance card and plan information accessible while traveling.
Save a digital copy of your insurance card and know where to find your plan information, provider network, and customer-support details. This can help you access medical care more easily after arriving in the US.
Start Your US Journey Prepared
Before traveling, review your immigration documents, check your Form I-20 and travel signature, research restricted items, and keep your paperwork organized and accessible.
A little preparation can help you approach US Customs and Border Protection with greater confidence and make your arrival experience smoother and less stressful.
