Some of what travels with an immigrating family cannot be replaced from abroad at any price. That set of things belongs in one bag that stays with the person, and it is worth being slightly obsessive about.
Checked luggage is delayed, misrouted and occasionally lost. None of that is a disaster for clothes.
Where this sits on the timeline
The packing week, and the airport. It is the last point at which the family controls where its documents are.
It is also the point where the first encounter with a United States agency takes place — at the port of entry — and what the person is carrying matters there in a way it has not mattered before.
What belongs in the hand-carried bag
The principle is simple: anything that would be difficult or impossible to replace from the United States.
- Passports and the visa documents themselves.
- Anything the consulate provided for presentation on arrival, including anything issued sealed — which stays sealed.
- Original civil documents: birth, marriage, divorce, adoption, and any official certificates obtained during the case.
- The vaccination record and any medical summary obtained before departure.
- Educational and professional records: diplomas, transcripts, licences, letters of employment.
- Prescription medication in its original packaging, with documentation from the prescribing doctor.
- Contact details on paper — the family in the United States, the address where the person will stay — in case a phone fails.
Everything on that list either cannot be obtained again from abroad, or requires a process that takes months from another country.
Educational records deserve a special mention
They feel less urgent than immigration documents, so they get packed in a box. Then, a year later, someone needs a transcript to have a qualification recognised or to apply for a course, and obtaining it from a university in Vietnam by post turns into a project.
Bring the originals. Bring more than you think you need. The cost of carrying them is nothing.
Copies, and where they live
Before anything is packed, photograph or scan every document in the hand-carried bag.
Store the copies somewhere reachable from any device, and make sure the family in the United States also has a set. The point is not legal validity — copies rarely have any — but the ability to know exactly what exists and what it says if the originals are delayed or mislaid.
A physical second set, carried by a different family member travelling together, is also worth doing where the family is travelling as a group.
What is hard to undo at this stage
An original lost in transit. Replacing a Vietnamese civil document from the United States is possible and slow; some older records cannot be reissued at all.
A sealed item opened. If anything was handed over sealed, it stays sealed until the moment it is handed to the officer who is meant to receive it.
Medication packed in a checked bag. If the bag is delayed, someone is without their medication in a country where they do not yet have a doctor.
The first encounter at the border is about what you carry
Entry is decided at the port of entry by U.S. Customs and Border Protection, separately from the visa decision. What matters there is documents, and — separately — what is in the bags.
Rules about what may be brought into the United States, what must be declared, and what is restricted are published by CBP, and they cover categories that surprise people: food, plant and animal products, traditional medicines, and items of high value.
This site does not list them, because the list is theirs and it changes. The rule that does not change: read the official guidance before packing, and declare anything the rules say to declare. Declaring something that turns out to be permitted costs a few minutes. Not declaring something that should have been declared is an entirely different kind of problem.
And do not carry items for other people
Requests to bring a package for a friend or a neighbour are common and should be refused without exception. Whatever is in the bags belongs, as far as the process is concerned, to the person carrying them.
What to start now for a stage two steps away
Two small things, packed deliberately, that matter in the first month:
- A written list of every document in the bag, so that the folder can be checked quickly and nothing is discovered missing weeks later.
- A note of what was left behind and where — with which relative, in which house. Families reconstruct this badly after a move, and it is the difference between a phone call and a lost record.
And keep the folder intact after arrival. The next chapter is largely about presenting documents from it, repeatedly, to different offices.
What must never go in checked luggage?
Anything hard to replace from abroad: passports and visa documents, anything issued sealed, original civil and educational records, vaccination records, and prescription medication.
Why bring educational records if they are not needed yet?
Because obtaining a transcript or diploma from Vietnam by post a year later becomes a project, and carrying the originals costs nothing.
What about food, medicines and other goods?
What may be brought in and what must be declared is published by U.S. Customs and Border Protection. Read it before packing, and declare anything the rules say to declare.
Should we carry a package for someone else?
No, without exception. Whatever is in the bags is treated as belonging to the person carrying them.
