I entered the USA on a three month visa waiver program from Australia. I am about to return to Australia and would like to come back again to the USA. How long do I have to wait until I can re-enter the USA for another 3 months?

    Do you mean as an Australian citizen or as some other citizen who just happens to be in Australia? I ask because we have tags for questions specifically about citizens from various countries. Nov 1, 2012 at 13:34

    You have to wait for your flight to arrive in Australia, and for you to get on your next plane back to the US. So, technically, about a day and a half. But you have to be able to justify your visit to the CBP officer. Apr 2, 2016 at 3:51

No fixed rule

There is no official rule on this. It is entirely up to the discretion of the Customs and Border Protection (CBP) officer dealing with you at the border as to whether you can or can't enter. This applies whether you have a visa, or if you wish to use the Visa Waiver Program (VWP) with an ESTA.

Guilty until proven otherwise

As far as I know, the prime directive of the border officer is to presume you intend to permanently live in the USA (i.e. immigrate there). It is up to you to prove otherwise. The amount of actual "proof" required may be very little. It could be (and normally is) as simple as your verbal statement that you intend to do XYZ whilst in the US, and intend to leave on a particular date. But, if you were very recently (like, less than 90 days ago) in the US for the maximum 90 days, it increases the probability the border officer will expect you to have greater proof you aren't abusing the WVP to live in the US.

Outbound ticket?

(With the VWP/ESTA) They may or may not ask to see a ticket to prove you intend to leave. You are, however, required to have one. So if they ask, and you don't have one, expect trouble. I would never suggest entering the US with an ESTA (under the WVP), without an outbound ticket. If your departure date is not fixed, and you want to enter on a one-way ticket, buy a refundable outbound ticket, and cancel it after you enter.

Causes for suspicion

There are scenarios that may increase the chances of triggering suspicion at border control.

For example, if the records show you have been spending more time in the USA than you have outside the USA, the CBP officer may decide you are mis-using the VWP system to "live" in the USA.

Another example, if you have previously stayed in the US for the maximum 90 days on the VWP, and then you return, let's say, within 12 months of your previous entry (although, it's totally at the discretion of the officer you deal with) this can alert them to questioning you more throughly. I know of numerous first-hand cases when that second scenario has played out. One was a friend from Sweden who stayed 89 days under the VWP. She returned 11 months later, to visit for another 80 to 90 days (which she told the officer), and she was taken aside for 3.5 hours of searching and questioning. She missed her connecting flight, and although she got in she had to go to great lengths to convince them she had zero intention or desire to immigrate there. Less than a year later she tried to return again, and was denied entry. She now needs a visa to reenter the USA.

In my experience, it's generally best to avoid staying the full 90 days if you plan to return any time soon (like in the next 3 to 12 months). I've seen numerous cases when that alone was the trigger for hassles on re-entry. I avoid staying more than 80 days, if I plan to soon return. But again, it's entirely up to the border official you happen to deal with.

Time in home country

The CBP officer might also take into account how much you are in your home country, as opposed to elsewhere. Someone re-entering the US after having recently left the US, who hasn't been to their home country for a significant period, is more likely to come across as someone who has poor ties to their home country, and therefore is more likely to try an immigrate to the US.

Ports can differ

My personal experience is that some ports of entry have officers with significantly stricter attitudes. Others are more relaxed. For instance, in my experience, the difference between entering the USA via Florida and New York is like night and day. I've entered through both on many occasions. I've also noticed a significant difference between LAX and SFO when entering on the West coast. Although, I will say recent (2015 to 2017) experience at LAX has been more relaxed. I always come and go through SFO if possible. It's not as much of a difference as MIA and FLL (both in Florida), but enough to warrant avoiding LAX and NYC if possible. Also the airport is less busy in SFO so that's a plus.

Consequence of denied entry

It is my understanding that if you are denied entry you will require a visa to return to the USA (and this will hold true for a period of 10 years). Receiving a visa will also be more difficult if you were refused entry at the border. You will likely have to go to much greater lengths (if even possible) to prove the validity of your reasons for visiting the USA, and applying for a visa. Caution is advised.


Simply put, the more you come across as someone who has no interest in immigrating the US, and with strong ties to your home country, the better. Which means, someone with definite ties to their home country (job, business, family, house, etc), and with a clear plan of travel in the US, and a clear departure date (within the 90 day allowance), the greater your chances the CBP officer will stamp you in without any hassle. Dress well, give clear answers, smile, cross all your Ts and dot all your Is, and chances are it'll be fine.

Ultimately, it all comes down to the discretion of the CBP officer.

    In more precise terms, the officer must "presume" rather than "assume" intention to immigrate. It's also worth noting that the specific requirement is to have a "round-trip ticket," but there is a regulation that defines this term such that any outbound ticket is acceptable if the destination is outside of North America (including "adjacent islands," if I recall correctly) or if the traveler resides in the destination country.

  • @Crazydre, unless something has changed (and it might of), that's different from what I know to be the case. I had a friend who had this exact issue. He was denied entry crossing by car from Canada to US. For 10 years he wasn't able to enter the US without a visa. My understanding is his normal entry requirements resumed after that period. This was, however over 20 years ago, so something might have changed. Do you have a reference? Sep 21, 2023 at 1:11
  • @FlyingKiwi Emailed the ESTA team a few years ago by email and was told that answering "yes" to whether you've ever been refused entry to the US will "routinely" trigger a denial after a manual review

There is no official rule for this, although there is a rule of thumb according to CBP. This is that if one spends X days in the US on the VWP, one should wait at least X+1 days before seeking to re-enter the US. Quoting from this Travel.SE answer on the topic:

CBP Rule of thumb between visits

the important paragraph reads:

The Visa Waiver Program doesn't work that way. If he decides to use the Visa Waiver Program (ESTA); maximum stay is 90 days and he needs to allow adequate time between visits. The rule of thumb is if he is in the US for 90 days; should be out of the U.S. for 91 days before returning.

    I don't think this letter supports a general "X+1 days" rule of thumb when X is not 90. For example, if someone travels to the U.S. for a 14-day business visit, then goes home for 7 days and comes back seeking entry for another 14-day visit, then I have trouble imagining that the border guards will turn him back for that reason -- especially considering that he would have been allowed to simply stay in the U.S. for the entire 5-week period instead. And even if this is a general rule, that fact is not reasonably implied simply by a single X=90 data point. Apr 20, 2016 at 9:23

    @HenningMakholm I think you're on to something. The general point is that someone should not appear to be living in the United States on the VWP. Someone who makes repeated visits for long periods of time will naturally lead officials to conclude he is living in the country. Two short business visits, especially if supported by a reasonable premise and documentation, seem unlikely to be a problem. Two longer visits are a problem. I think the advice more broadly is "spend as much time out of the country as you do in it" and the "X+1 days" is a rule of thumb. Apr 20, 2016 at 16:50

I think you can enter again the day after you left. I remember entering again about 100 days after I entered the first time (so not long after the end of the 90 days, but a while after I left the country) and I have friends who entered a lot of times and on a regular basis so they probably had maybe 2 weeks between the time they left US (and gave their I-94 back) and they entered again (filling a new I-94). We were all European and part of the Visa waiver program.

Be careful, though, to do the ESTA procedure if you arrive by plane (likely in your case).
