Traveling to Poland via Berlin

Hello, I am a university student and I will start my Erasmus+ program in Poland Poznan in September. The thing is, plane tickets from my country to Poznan is 390 euro while plane tickets to Berlin is 148 euro, which is an incredible difference. I want know if it is possible to do the first landing to Europe in Berlin and get a bus to Poznan. Once somewhere I heard that one must first land on the country which they took the visa from, which in my case Poland. Would it be problem if I did my first landing to Europe in Berlin?

Thank you so much, and sorry for any mistakes in my writing.

You can certainly take a train between Berlin and Poznan, because I did it a few years ago. From memory it took a couple of hours or so.

Re the visa question. I'm going to leave it to the immigration experts on here, but can you clarify because they will need to know in order to help you: What is your nationality? And I think your visa should be a student visa issued by Poland, not a Schengen tourist visa?

My nationality is Turkey and just as you said it is a student visa. It is D type with multiple entries.

Well as I said previously, I'm not an immigration expert, so don't celebrate till someone better comes along with an opinion, but...

I think you'll be fine travelling via Germany.

I can't find anything which requires you to enter the Schengen zone via Poland.

And I have found this in the Schengen Borders Code:
"(b) they are in possession of a valid visa, if required pursuant to Council Regulation (EC) No 539/2001 of 15 March 2001 listing the third countries whose nationals must be in possession of visas when crossing the external borders and those whose nationals are exempt from that requirement ( 18 ), except where they hold a valid residence permit or a valid long-stay visa"

I think your long-stay visa gets you in through any Schengen port of entry.

Perhaps someone will tell me this is out of date or incorrect?

Edit: I've also found this:
"third-country nationals who do not fulfil all the conditions laid down in paragraph 1 but who hold a residence permit or a long-stay visa shall be authorised to enter the territory of the other Member States for transit purposes so that they may reach the territory of the Member State which issued the residence permit or the long-stay visa"

It seems long-stay makes it possible or at least much less risky. Thank you so much for all the information, as you said I must not celebrate early, but it helped me to feel at ease a little bit.

I will try to look more into the codes you found for any other possibility.

Hello. I did just that on my last trip to Europe. Though it was the other way around, travel to Berlin via Poland. I took the train from Warsaw to Berlin. So you could do the same. And if your leaving for Poznan, the the length of the trip is about half the duration to Warsaw.

Poland and Germany are both in Shengen, so having a visa that covers shengen will allow you free travel between both countries.
