Teaching in more than one country is normal in this work. Almost everyone does some version of it: a winter somewhere warm, a home city, a summer month where the retreats are, a family country you go back to.
Describing it is the hard part. Say too little and you look like you have no base. Say too much and you look like you're claiming to be in four places at once, which reads as unserious to exactly the people you want booking you.
The two failure modes
The first is looking rootless. A page that says "teaching worldwide" or lists nine cities with no dates tells a studio nothing except that you are probably not here. Studios book people who exist near them. A host looking for someone in Athens next Tuesday will not spend energy working out whether you might be.
The second is looking like you overstate things. This is worse, and it's the one nobody warns you about. If your page implies you're regularly available in Berlin, Lisbon and Mexico City, and someone writes to you in Berlin and you reply that you're actually in Oaxaca until April, you haven't just lost that booking. You've taught them that what you say about yourself needs checking.
Both of these come from the same root: describing places instead of describing time.
Pick a base, even if it's only two thirds true
Someone reading about you is trying to answer one question in about five seconds: where is this person, mostly.
Give them an answer. One city, first, plainly. Not because it's your whole life but because a base is what makes the rest of it legible. "Based in Lisbon, regularly in Berlin and Athens" is a person. "Between Lisbon, Berlin and Athens" is a fog.
Choose the city where you'd most like to be booked, or the one where you actually spend the most nights. If it genuinely splits down the middle, pick the one where you have the most working relationships, because that's the one where a name check will land.
The rest of your countries don't disappear. They move down one line, into a pattern.
Describe a pattern, not a map
Almost everyone's travel is a shape that repeats. Say the shape.
"Based in Lisbon. In Berlin for most of May, June and September, teaching guest classes and workshops. In Kerala every January and February. Available for retreats anywhere from March onward."
That paragraph does an enormous amount of work. A Berlin studio planning summer knows to write to you. A retreat host planning a January week knows not to. Nobody has to guess, and nothing in it will be wrong in six weeks.
A pattern also survives your own life changing. If May in Berlin becomes June in Berlin, you edit four words. If your page is a list of eleven specific events, half of it is a lie by August.
That is the actual reason multi-country pages rot. Not neglect. Dated content ages into wrongness on its own, and the more countries you list the faster it happens. Anything you write that will still be true next year is worth ten of anything that expires.
Seasons are an advantage, if you say them out loud
Every teaching city has a dead stretch. August empties out in a lot of European cities. January is quiet in the places people leave in winter and packed in the places they go to. Studios know their own dead months and dread them.
A teacher who reliably appears in someone's quiet season is more valuable than one who appears in the busy one, because the busy one is already covered by locals.
So when you write, name the season and not just the dates. "I'm in Berlin for most of August, which I know is quiet, and I'd be happy to hold something small or cover for teachers who are away" is an easier yes than the same offer in October.
Being predictable in one boring month, two years running, is what turns a visitor into part of a schedule.
One line, with a date in it
The single most useful thing on the page of somebody with a split life is a current location line with a date attached to it.
"Right now: Lisbon, until 15 October. Then Berlin, 16 October to 30 November."
Two things make it work. It is specific enough to act on, and the date tells the reader how fresh it is. A visitor in November who sees a line ending 30 November knows you keep this updated. A visitor who sees a line that expired in March knows the opposite about everything else on the page too.
The rule: if you can't update that line once a month, don't have it. A stale "currently in" is worse than no line at all, because it actively misinforms someone who was ready to book you.
If once a month is unrealistic, write the pattern instead and skip the live location. The pattern is never wrong.
Time zones, and the speed that actually matters
If you teach or hold sessions online, or take one-to-one clients across countries, say your working hours in the reader's terms and not yours.
"One-to-one sessions Tuesday to Thursday, 8am to 1pm Lisbon time, which is 9am to 2pm in Berlin and 3am to 8am in New York."
Nobody does the arithmetic for you. They do it for themselves, get it slightly wrong, feel stupid, and don't write.
The other half of this is reply speed. When you live across time zones, the honest constraint is that a message can sit unread for fourteen hours through no fault of yours, and the person who sent it doesn't know that. Say it, once, wherever people write to you from: "I'm usually a day behind on messages, and sometimes two if I'm traveling. I do answer." A studio manager who knows that will wait. One who doesn't will assume you're not interested and message somebody else by Thursday afternoon.
Being honest about which country you're actually good in
There's a difference between the countries you visit and the countries where you can work.
You can work where you have the relationships: studios that have had you, a host who knows your name, enough language to teach comfortably, a way to get paid, and whatever permissions actually apply to your situation there. That last one varies enormously by country and by your own passport, and it is worth checking properly rather than assuming.
Everywhere else, you are available to be invited. That's still worth saying, and it's a different sentence.
"I teach regularly in Portugal and Germany. Elsewhere I'm available for retreats and workshops as a guest, and I've done that in Greece, Morocco and Sri Lanka."
That is a completely honest description of an international teaching life, and it sounds bigger and more solid than a list of eleven flags, because a reader can tell which parts are established and which are open.
When the plan changes, and it will
It always changes. The visa took longer, the retreat moved, you fell in love in a different country.
Two habits keep this from eroding what people think of you.
First, edit the pattern before you announce anything else. Ten minutes, four words.
Second, tell the specific people who were counting on the old plan, before they find out from the page.
"Quick heads up: I'd said I'd be in Berlin in May and that's moved to June. Nothing dramatic, just a change of dates. If you were thinking about the guest class, June 3rd to 20th is open and I'd still love to."
That message costs nothing and it does something small and important: it makes you a person whose stated dates mean something. Over a few years that's worth far more than any single booking, because the studios that keep booking traveling teachers are the ones who've learned that a particular teacher's yes is reliable.
The smallest version of all of this
You don't need a country page or a booking calendar or a system.
You need three sentences that a stranger can read in ten seconds and act on: where you are based, when you are in your other places, and what you're open to being asked for. Written so that they'll still be true next spring.
"Based in Lisbon. In Berlin most of May and September, and in Kerala in January. Open to guest classes, workshops and second-teacher work on retreats, anywhere."
Update those three sentences twice a year, in January and in July, with a reminder in your calendar so you don't have to remember. That is the entire maintenance cost of being genuinely bookable in three countries, and it is roughly twenty minutes a year.
Most teachers spend more than that rewriting a bio nobody asked to read.
