По истечении проверки заявитель получит временное удостоверение.

It is a formal time expression meaning after the check has been completed or upon completion of the check.

Literally:

• по = a preposition
• истечении = expiration / completion / lapse in the prepositional case
• проверки = of the check / verification in the genitive case

So the structure is roughly:

• по истечении чего? = after the completion of what?
• по истечении проверки = after the completion of the check

This is a very official, bureaucratic way to say after.

Because the preposition по in this expression requires the prepositional case.

The base noun is:

• истечение = completion, expiration, lapse

Its prepositional singular form is:

• (по) истечении

So:

• по истечении = upon / after the completion

This is a fixed formal phrase you will often see in official language.

Because истечение takes a dependent noun in the genitive:

• истечение чего? = completion of what?
• истечение проверки = completion of the check

Then in the full phrase:

• по истечении проверки

So the case chain is:

• по → makes истечении prepositional
• истечении → governs проверки in the genitive

This is very common in Russian noun phrases.

They are close in meaning, but not identical in tone.

• после проверки = after the check
  More neutral and common in everyday language.

• по истечении проверки = upon completion of the check / after the check has run its course
  More formal, official, and bureaucratic.

So in everyday conversation, a person might say:

• После проверки заявитель получит временное удостоверение.

But in official notices and legal-style writing, по истечении проверки sounds more natural.

Because получит is future tense of the perfective verb получить.

Here the sentence describes a single completed future result:

• the applicant will receive a temporary certificate

That is why Russian uses perfective future:

• получит = will receive

Compare:

• получает = receives / is receiving (present, imperfective)
• будет получать = will be receiving (future, imperfective; focuses on process or repeated action)
• получит = will receive (future, perfective; focuses on the completed outcome)

This sentence is about the result, so получит is the natural choice.

Because заявитель is the subject of the sentence — the person who performs the action of receiving.

• заявитель = the applicant
• получит = will receive

So:

• кто получит? = who will receive?
• заявитель

That makes it nominative singular.

It is the direct object of the verb получит, so it is in the accusative case.

However, for an inanimate neuter singular noun, the accusative form is the same as the nominative.

So:

• временное удостоверение can be nominative or accusative
• here it is accusative because it is the thing being received

Breakdown:

• временное agrees with удостоверение
• both are neuter singular
• both appear in the accusative form here

Удостоверение is a formal document that certifies or identifies something. In many contexts it can mean:

• certificate
• ID document
• credential
• official document

In this sentence, временное удостоверение usually means something like:

• temporary certificate
• temporary ID
• temporary document

The exact English translation depends on the real-world context. It is not necessarily a passport or a license; it is simply an official temporary document.

The word order is natural, but Russian is flexible.

Current order:

• По истечении проверки заявитель получит временное удостоверение.

This puts the time phrase first, which is very common in official writing. It emphasizes when the action happens.

You could also say:

• Заявитель получит временное удостоверение по истечении проверки.

This is also correct. It sounds slightly less front-loaded and a bit more straightforward.

So the meaning stays the same, but the original version sounds especially formal and document-like.

Yes. Проверка is a broad word and can mean:

• inspection
• verification
• review
• check
• background check
• examination of documents

In this sentence, the exact type of check is not specified. It depends on context. For example, it could be:

• a document check
• an eligibility check
• a background verification
• an administrative review

So проверка is intentionally general here.

Yes, very much so.

Several things make it sound official:

• по истечении instead of the simpler после
• заявитель = a formal word for applicant
• удостоверение = an official document term
• the overall compact, impersonal style

A more everyday version might sound like:

• После проверки заявитель получит временный документ.

But the original sentence is exactly the kind of wording you might see in a government notice, administrative instruction, or legal-style text.
