Germany is one of the best european country to live, work, study and do business.
Germany offers ‘golden visa’ to  entrepreneurs who invest in a German venture and create jobs.  German passport is rated as the No.1 passport in the world in 2017 visa restrictions index with visa free access to 176 countries in the world.
Golden visa applicants are successful if authorities consider that there is a national or regional economic interest in their admission to the country, that the proposed activity would be favourable for the economy, and the financing of the venture has been guaranteed through the investors’ own funds or confirmed loans.
Investment conditions
German law does not specify a particular amount that an investor must bring to Germany in order to obtain a residence permit. From January 1, 2009, until July 31, 2012, German law allowed for the granting of a residence permit to a foreign entrepreneur who, in addition to meeting other criteria, invested at least €250,000 (about US$325,000) in a German venture that created at least five new jobs.
A reform law that went into effect on August, 1, 2012, eliminated these numerical conditions and entrepreneurs are currently admitted into Germany if an evaluation of their intended entrepreneurial activities indicates that there is a national or regional economic interest in their admission, the proposed activity would be favorable for the economy, and the financing of the venture has been guaranteed through the investors’ own funds or through promised loans.
