ESTA & B1 Visa: Visa Waiver and the US Visitor Visa

IMPORTANT: As a rule, we advise clients who can use ESTA not to apply for a B1 visa. If you are eligible for ESTA and still apply for a B1 visa, you make yourself look "suspicious", and there is a fairly high chance the B1 visa will be refused. Once you have had a US visa refused, you can never again enter the USA visa-free for the rest of your life. So only apply for the B1 visa after carefully weighing the pros and cons, and only if your attorney considers it safe.

ESTA and B1 both work for shorter business stays in the USA. The Visa Waiver Program is not a visa but a travel authorization. It is straightforward and gives entrepreneurs plenty of options. With ESTA you can spend up to 90 days at a time in the States, with multiple entries if needed and no new application. If you need more than 90 days, the B1 visa is a good alternative. It lets you stay up to 180 days per entry in the USA, but the application takes more effort.

Here you will find out which business activities each of these two categories covers and which one you should choose for your plans. We also look at the reasons that speak for or against each option.

More information plus tips & tricks for your ESTA application are here.

1What are ESTA and the B1 visa?

The B1 is a US visa, while ESTA is an electronic travel authorization system. Under the Visa Waiver Program, authorizations are issued that let holders enter the States without a visa. The basic requirement for an ESTA application is that your home country takes part in the Visa Waiver Program.

Once approved, ESTA is valid for two years (or until your passport expires); during that time you can use it as often as you need, for stays of up to 90 days at a time. So how long your ESTA lasts also depends on your passport: if it expires before the two years are up, the authorization ends too.

The B1 is a visitor visa for business travelers. It lets you stay in the USA for up to 180 consecutive days. It is the right choice for anyone excluded from the Visa Waiver Program. Compared with ESTA, the visa naturally means longer lead times for the application and higher costs. The B1 visa is usually valid for 10 years and allows multiple entries into the States during that period.

2How ESTA and the B1 visa differ

For entrepreneurs traveling to the USA on business, ESTA and the B1 visa allow essentially the same activities. The only real difference is the maximum length of stay: with ESTA you may stay just 90 days at a time, with the B1 it is 180 days.

Besides the length of stay, the application processes differ too. With the Visa Waiver Program, business travelers save the cost and effort of a visa application. You simply apply through an online form. It is cheaper and, unlike the B1, needs no in-person appointment at a US consulate. So if you want to apply for a US B1 visa, plan for the consulate interview, a longer lead time and higher costs.

3What you may do on ESTA and B1

In general, both ESTA and the B1 allow business activities in the States. Visa-free entry under the Visa Waiver Program is especially popular for business trips: it is more flexible and saves time and money compared with applying for a visa.

Business trips are any trips that advance commercial or professional interests in the USA without involving local employment or payment from US sources. If you fly to the USA on business, still check carefully in advance which activities are legal. That applies to entry on ESTA as well as on the B1. According to the US State Department, ESTA and B1 holders may:

  • attend business meetings
  • carry out business-related research
  • consult with business partners
  • attend trade fairs, conventions & conferences
  • negotiate contracts
  • prepare projects
  • settle estate matters

Both options give entrepreneurs traveling to the USA the same rights for business trips. The Visa Waiver Program involves less red tape, though, so where possible it is the better choice.

Because the lines between categories are often blurred, check each case carefully to see whether your particular business activity is really covered by ESTA and B1. That way you avoid trouble with US authorities.

If you travel to the USA often and for long stays on ESTA, be ready for border officers to ask exactly why you are coming. It is also wise to carry documents that back up the activity.

Important: On both ESTA and the B1 visa, you may not take jobs from US clients or receive pay from US sources. You also cannot carry out unpaid assignments for US companies. The precise definition: your activity must not take a job opportunity away from a worker based in the States. If you want to do productive work in the USA, look at a work visa instead, such as the E-1 treaty trader visa, the O1 visa for experts or the L-1 visa for intracompany transfers.

4When B1 beats ESTA

If you already hold a valid ESTA or live in a participating country, it is usually best to stick with ESTA and avoid a B1 visa. One reason: if your visa application is refused, future ESTA applications will very likely be refused too. If you already had ESTA approval, you must reapply for ESTA after a failed visa application and risk that being refused as well. Still, there are certain reasons that justify a visa application even when you are ESTA-eligible:

  • Longer stays: If 90 consecutive days in the States under the Visa Waiver Program are not enough, the B1 is a solid alternative.
  • Criminal record: People with a criminal record must have a US visa to enter and should therefore go for the B1.
  • Nationality & travel: Some nationalities are excluded from the Visa Waiver Program. Previous stays in certain countries can also rule out ESTA and make a B1 visa necessary.
  • Refused entry: In general, ESTA lets you enter the USA several times a year. How often is ultimately at the border officers' discretion, though. If you have had problems entering in the past, for this or any other reason, the B1 visa is the better choice.

5ESTA or B1: what this means for you

Our experience shows: you don't always need a visa to do business in the USA. ESTA gets you into the States with little hassle and opens up plenty of opportunities, which is why we are happy to recommend this visa-free route. Thanks to the Visa Waiver Program, many of our clients spend 6 months a year in the USA. With ESTA you have the same rights as with a B1 visa. If you need longer stays at a time or cannot get ESTA, the B1 visa is usually a good alternative for business trips across the pond.

You'll find every route to the USA in our visa overview. If your business trip is meant to become something more, take a look at the E-2 investor visa.

In short
  • ESTA is not a visa but an electronic travel authorization under the Visa Waiver Program; it is valid for two years and allows stays of up to 90 days at a time.
  • The B-1 is a visitor visa for business travel with up to 180 days per entry, but it requires a consulate appointment, more lead time and higher costs.
  • Both allow the same business activities, such as meetings, trade fairs and negotiations, but no work for US clients and no pay from US sources.
  • If you can use ESTA, only apply for a B-1 after careful consideration, because a refusal also puts future ESTA applications at risk.

Frequently asked questions

Is ESTA a visa?

No. ESTA is an electronic travel authorization system under the Visa Waiver Program. It lets citizens of participating countries enter without a visa.

How long can I stay in the USA on ESTA?

Up to 90 days at a time. The authorization is valid for two years or until your passport expires, and you can use it multiple times during that period.

How long can I stay on the B-1 visa?

Up to 180 days per entry. The B-1 visa is usually valid for ten years and allows multiple entries during that time.

Can I work in the USA on ESTA or a B-1?

No. Business activities such as meetings, consulting with business partners, trade fairs, conferences and contract negotiations are allowed. Work for US clients and pay from US sources are not allowed on either; if you want to do productive work in the USA, you need a work visa.

Should I apply for a B-1 visa if I'm eligible for ESTA?

Usually not. If your visa application is refused, future ESTA applications will most likely be refused too. A B-1 makes sense if 90 consecutive days are not enough for you, if you have a criminal record, if you are excluded from the Visa Waiver Program or after problems on earlier entries, and only if your attorney considers it safe.
