Law / Non-EU citizen, student, prolonging Polish National Visa [4]

Hello,

I am a Turkish citizen and I am still studying in an University as an exchange student. I have D-Type Polish Visa, which is valid until 1 March. But I will stay one more semester in Poland, so i need to prolong my visa at least until January (more than 3 months).

My question is, can I prolong my national visa in Poland (i mean, without going back to turkey) without getting temporary residence card.
In brief: I want to prolong my visa without applying for temporary residenceship.

And which department I should go? Foreigners office or what?

Thank you.

Life / What happened to my mail? (I sent some documents to Warsaw from Turkey.) [3]

Hi dear friends!

I have a problem with my post-mail. I sent some documents to Warsaw from Turkey. I have a tracking number. I am entering this number to the polish post website ( sledzenie.poczta-polska.pl/ ), and webpage says my post is at warsaw customs. It's waiting there since 6 days! Is this a normal time?

I also checked with same tracking number on a website called pocztex.pl , there was no result. Web page said "Brak przesyłki o podanym identyfikatorze".

What is going to be my post?

Thank you very much.
