Capitalize all words in title.

Turkish citizens have suffered from the same problem related visavisa-related problems for years, which complaintspeople in the post complain about.

You suffer FROM something. ie I suffer FROM back pain. I suffer FROM headaches.

you need the word 'to' to show what the problem is coming from.

Here I would say 'visa-related problems'. If you want to say that they have suffered for a long time (for years) you need HAVE suffered before (present continuous) because it is still happening.

PEOPLE are the ones who are complaining.

Particularly, Schengen Ccountries, the UK, the USA ask for multiple documents such as payslips, savings statements, proof of assets, etc for visa application. from applicants.

You ask FOR something. 'Can I ask FOR a cookie?'

As a bank term, savings is plural. "Can I see your savings account?"

We already know you're talking about visa applications, so it sounds more natural to just say 'from applicants'.

BesidesEven so, it is not assured you will get a visa if you submit all the necessary documents.

Even so would be a better introductory word here, because EVEN if you do all of that you might not get it.

Need preposition words to introduce the noun. 'A visa'. 'THE necessary documents'.

Turks are humuiliated by these countries but the competent authorities does not take any actions againist this humilidiscrimination.

subject verb agreement. ...competent authorities DO not......

Discrimination would be a better word here because this process is very unfair towards Turkish citizens.

On the other hand, citizens of these countries can enter Türkiye even without a pasasport, just an ID card is enough.

Citizens is plural because you are talking about multiple people.

Again preposition for 'a' passport.
AN ID card.

Also added the word 'just' to indicate how they ONLY need an ID card.

From Türkiye's perspective, the principle of reciprocity is not requirfulfilled in the visa process.

THE principle of reciprocity.

You might want to say fulfilled instead of required here.
