Mana mungkin saya bisa lewat imigrasi kalau visa saya belum keluar?

In this sentence, mana mungkin is an idiomatic expression meaning how could that be possible?, no way, or that’s impossible.

• mana by itself often means which or where, depending on context
• but in mana mungkin, it does not literally mean where
• the whole phrase works as a fixed expression of disbelief

So Mana mungkin saya bisa lewat imigrasi... means something like:

• How could I possibly get through immigration...?
• There’s no way I could get through immigration...

It is a very natural, conversational way to show that something is clearly impossible.

Bisa usually means can, be able to, or be possible to.

Here it adds the idea of possibility/ability:

• saya lewat imigrasi = I go through immigration
• saya bisa lewat imigrasi = I can / would be able to go through immigration

Because the speaker is talking about whether passing immigration is possible, bisa is very natural.

In English, the sentence is not just about the action itself, but about whether that action is possible under the circumstances.

Lewat literally means to pass, to go past, or to go through.

So lewat imigrasi means to go through immigration or to pass through immigration control.

This is a common everyday way to say it. It is fairly conversational.

Depending on context, you might also see more formal or specific alternatives, such as:

• melewati imigrasi
• lolos imigrasi = to get past immigration / clear immigration

But lewat imigrasi is very natural in speech.

Both kalau and jika can mean if.

The difference is mainly tone:

• kalau = more common in everyday conversation
• jika = more formal, more written, sometimes more official-sounding

Since this sentence sounds like natural spoken Indonesian, kalau fits very well.

So:

• kalau visa saya belum keluar = if my visa hasn’t come out / hasn’t been issued yet

Using jika here would still be grammatical, but it would sound a bit more formal.

This is a very common thing learners ask, because keluar usually means to go out or to come out.

In administrative or bureaucratic contexts, keluar can also mean:

• to be issued
• to come out
• to be released
• to be ready

So visa saya belum keluar means something like:

• my visa hasn’t been issued yet
• my visa isn’t out yet
• my visa hasn’t come through yet

It does not mean the visa physically walked out somewhere. It is an extended meaning that is very common in Indonesian.

You will hear similar expressions with documents, results, and permits.

It usually means the visa is not ready / not issued / not out yet.

Exactly how to translate it depends on context:

• it may mean it has not been officially issued yet
• it may mean the result has not come out yet
• it may mean the document has not been processed to the point where it is available

So it is slightly broader than just I haven’t received it yet.

If someone wanted to emphasize physical receipt, they might say something more like:

• visa saya belum saya terima = I haven’t received my visa yet

But belum keluar often focuses on the visa’s status in the system, not only whether it has reached the speaker’s hands.

Yes, this is a very common pattern.

Mana mungkin + clause is a set expression used to reject an idea as impossible or unrealistic.

Pattern:

• Mana mungkin + subject + predicate...?

Examples:

• Mana mungkin saya tahu? = How would I know?
• Mana mungkin dia datang sekarang? = How could he come now?
• Mana mungkin kita selesai hari ini? = There’s no way we finish today.

So in your sentence:

• Mana mungkin saya bisa lewat imigrasi... = How could I possibly get through immigration...?

It is less of a real information question and more of a rhetorical statement of impossibility.

It is mostly conversational / everyday Indonesian.

The clues are:

• mana mungkin sounds natural and spoken
• kalau is the everyday word for if
• lewat imigrasi is a common spoken way to say go through immigration
• belum keluar is also a very natural everyday expression for a visa not being issued yet

A more formal version might be something like:

• Bagaimana mungkin saya dapat melewati imigrasi jika visa saya belum diterbitkan?

That sounds much more formal and official.

So the original sentence is correct and natural, but it is not especially formal.

Yes. Both can express how is that possible?, but they feel a bit different.

• bagaimana mungkin = more literal how is it possible, often slightly more formal or neutral
• mana mungkin = very common, conversational, and often stronger in tone, like no way

Compare:

• Bagaimana mungkin saya bisa lewat imigrasi...?
  More neutral, still natural

• Mana mungkin saya bisa lewat imigrasi...?
  More colloquial and emphatic

So the original choice makes the sentence sound very natural in speech.

Because belum already includes the idea of not yet.

That is one of the most important Indonesian words to learn:

• sudah = already
• belum = not yet

So:

• visa saya belum keluar = my visa has not come out yet / has not been issued yet

You do not need an extra separate word for yet in most cases. The meaning is built into belum.

Yes. In this kind of sentence, imigrasi usually refers to the practical travel process of immigration control at the airport or border.

So lewat imigrasi is understood as:

• going through the immigration checkpoint
• passing immigration inspection
• clearing immigration

Indonesian often uses the shorter noun imigrasi in this practical way, just as English speakers say go through immigration.

Sometimes yes, if the context is already clear.

For example, in conversation someone might say:

• Mana mungkin bisa lewat imigrasi kalau visa belum keluar?

That still sounds natural if everyone knows who is being talked about.

But including saya makes the sentence clearer and more complete:

• Mana mungkin saya bisa lewat imigrasi kalau visa saya belum keluar?

Also, repeating saya in visa saya is normal. Indonesian often repeats possessors where English might rely more on context.
