Ya tengo la cita previa para renovar el pasaporte mañana.

Ya usually means already here. It tells you that the speaker has completed something they wanted or needed to do: they now have the appointment booked.

It often adds a small nuance of progress, relief, or satisfaction:

• Ya tengo la cita previa = I’ve already got the appointment booked
• without ya: Tengo la cita previa = a more neutral I have the appointment

So ya is not required for grammar, but it adds meaning.

Cita previa is a very common expression in Spain, especially in official or administrative contexts. It means a pre-booked appointment, often one that you must arrange before going to an office.

You will often see it for places like:

• passport offices
• police stations
• town halls
• immigration offices
• medical services

Literally, it is something like prior appointment, but in natural English it is usually just appointment or pre-arranged appointment.

Because Spanish normally says to have an appointment just like English does.

• Tengo una cita = I have an appointment

So Ya tengo la cita previa is completely natural structurally: the speaker has the appointment.

Because para + infinitive is a very common way to express purpose in Spanish.

• para renovar el pasaporte = to renew the passport / for renewing the passport

After para, Spanish often uses the infinitive when the subject stays the same:

• Estudio para aprender = I study to learn
• Llamé para preguntar = I called to ask

So here:

• la cita previa para renovar el pasaporte = the appointment to renew the passport

Spanish often uses the definite article (el, la, los, las) where English might use a possessive like my.

Here, el pasaporte is natural because it is obvious whose passport is meant: the speaker’s.

So both are possible:

• renovar el pasaporte = natural and common
• renovar mi pasaporte = also correct, a bit more explicit

Spanish does this quite often when possession is clear from context.

Here it means tomorrow.

That is clear from context, and also from form:

• mañana = tomorrow
• la mañana = the morning

So:

• mañana voy = I’m going tomorrow
• por la mañana = in the morning

In your sentence, mañana is understood as tomorrow.

Spanish word order is flexible, and putting mañana at the end sounds very natural.

The sentence flows like this:

• Ya tengo la cita previa = main idea
• para renovar el pasaporte = what the appointment is for
• mañana = when it is

You could move it:

• Mañana ya tengo la cita previa para renovar el pasaporte
• Ya tengo mañana la cita previa para renovar el pasaporte

But the original version is very natural and easy to understand.

Yes, and in many situations that may sound even more natural.

There is a small difference:

• Ya tengo cita previa = I’ve already got an appointment booked (more general)
• Ya tengo la cita previa = I’ve already got the appointment booked (more specific, as if referring to a particular one)

In everyday Spanish in Spain, people very often say:

• Ya tengo cita previa
• Ya tengo cita para renovar el pasaporte

So the version with la is possible, but without it is also very common.

Because the speaker is talking about a present fact: right now, they have the appointment.

The appointment itself happens tomorrow, but the possession of that appointment is true now.

So:

• tengo = I have now
• mañana = the appointment is for tomorrow

This is very natural in both Spanish and English:

• I have an appointment tomorrow
• Tengo una cita mañana

Yes, especially because cita previa is very typical Spanish administrative language.

That said, depending on context, some speakers might more commonly say:

• Ya tengo cita previa para renovar el pasaporte mañana.
• Ya tengo la cita para renovar el pasaporte mañana.

So your sentence is understandable and natural, but in casual use many people might drop la or simply say cita instead of la cita previa, depending on how specific they want to be.

In practice, it refers to the whole appointment event taking place tomorrow.

Since the purpose of the appointment is renovar el pasaporte, the listener understands that the passport-renewal appointment is tomorrow.

So even if grammatically mañana comes after renovar el pasaporte, the natural interpretation is:

• the appointment to renew the passport is tomorrow

If you wanted to make that timing even clearer, you could say:

• Ya tengo la cita previa de mañana para renovar el pasaporte
• Ya tengo cita previa para mañana, para renovar el pasaporte
