If you plan to study in Germany, you have to submit an application for a student visa to the respective German mission abroad before travelling. The same applies to holders of most national residence permits and national category D visas issued by individual Schengen states for long‑term visits of more than three months. A separate visa may well be needed for travel to other EU states which are not Schengen states. The mission abroad decides what type of visa to issue on the basis of the documents submitted. If necessary, it may issue a visa that entitles the holder to enter the Schengen area on multiple occasions within the given period of validity. Please note that regardless of the length of validity, visas only entitle the holder to a maximum stay of 90 days in any period of 180 days.

As holder of a residence permit issued by a Schengen country, you need no visa for short-term stays in other Schengen countries - so you need no visa for Germany either. In any 180 days period you may stay for up to 90 days maximum in another Schengen country. Please check with the relevant authorities in your country of residence whether your spouse's residence permit entitles him or her to visa-free travel within the Schengen area.

Private universities in all federal states may also charge tuition fees.

These include, for example, the so-called LL.M degree programmes for law students. Fees for these programmes are sometimes very high so you should find out about them in advance.

So whenever you come across verbs and/or prepositions in connection with personal pronouns it is very useful to remember these forms well because most of the time it is the only form that exists. That is, forms like "mit dich", "ohne dir", "dir kennen", "dich antworten" do NOT exist.

Which grammar case we have to use in a sentence is determined by the verb or preposition of our phrase. Let's have a look at some examples with very common prepositions and with a few verbs. Amisan+dem.Ancan be used as "on" or "at." Note thatamis whenanis used with the dative , butancan also be used with the accusative.

One recurrent topic of discussion is the spread of anglicisms throughout the German language.

Fundamental to learning any language is becoming familiar with how to talk about days, weeks, months, and years. It's not necessarily a word you'll use everyday, but it's one you'll see often. It's also a very versatile word, so learning the different meanings ofzuand how it works is crucial to expressing yourself fluently in a variety of situations. Very often I can realize that learners of German struggle with using the correct form of the 1st person and 2nd person personal pronouns in the singular.

Both "me" and "you" have each two translations in German. "Me" can mean either mich or mir and "you" can mean either dich or dir. The difference between these forms is their grammar case. Mir and dir are DATIVE personal pronouns and mich and dich are ACCUSATIVE personal pronouns.

Now you've read about the difference between 'since' and 'for', try writing some personal examples using each one. For example, describe how long you've lived at your present address, or how long you've worked/studied at your present company or school. By writing these examples you'll reinforce what you've learnt and you'll be able to use these words much more easily in conversation. Beican be translated as "at," "during," "near" and "with," and is always followed by the dative - which is why you will also seebeicombined withdemto formbeim.

Germany is attracting students from all corners of the world towards its excellent universities.

The strong influence of Kiezdeutsch, roughly 'street German', on the language used by many young people inside and outside the immigrant community is particularly controversial. However, this form of 'youth-speak' is seen by many language researchers as less of a threat and more as an enrichment of the German language and identity. In 2004, the most beautiful German word of the year was the somewhat old-fashioned Habseligkeiten. The term, the jury explained, was selected as it refers to a mix of earthly possessions and the state of bliss that is unattainable while still on earth.

This interesting juxtaposition of concepts, the jury continued, inspired positive emotions in the reader towards the owner of said Habseligkeiten. The capacity to feel love towards small things of little value suggested a capacity for happiness. The way we express ourselves determines how we as individuals, as a generation, as a group or as a nation behave and are perceived.

To what extent this is the case becomes apparent when we talk to people whose native language is not our own. The differences in the way they use the language are often surprising, and can give us a clue as to how different their patterns of thought and their identity are from ours.
