As an EU citizen, you may enter Germany to look for work and stay in Germany (§ 2 para. 1 No. 1a Law on the general freedom of movement of citizens of the Union (FreizügG/EU)). All you need to enter the country is a valid passport or identity card.  After a stay of more than 3 months, the Foreigners authority can ask you to substantiate the requirements for exercising the right to freedom of movement. This means that you have to declare that you are looking for a job, but you do not (yet) need to submit any supporting documents. Only after a stay of more than 6 months can the Foreigners authority ask you to prove your efforts to find work and your chances of success on the job market.

Personal data are usually taken from national passports or ID cards, no translations are needed here. However, relationships under family law are regularly verified by means of civil status documents (marriage, birth and death certificates) and then entered.

International versions of marriage, birth and death certificates can be issued in some of the EU countries that have signed the Convention on the issuance of multilingual extracts from civil registers of 8 September 1976. These international documents are recognised in the Member States of the Convention without any further formalities (legalisation or apostille endorsements).

Documents from other countries must be correctly certified in the home country and then translated into German by a sworn translator. The authentication can be done either by the competent authority in your home country (apostille) or by the responsible German diplomatic mission abroad (legalisation).
