What are the advantages of finding a foreign girlfriend?

There is no great benefit. If both parties hold green cards of relevant countries, they can enjoy some preferential policies of relevant countries. If both parties are China citizens and get married abroad, the relevant laws of the place of marriage will be automatically applied and protected by the local laws of the place of marriage. After marriage, you must go back to China to go through the relevant certification procedures, otherwise China will not recognize and protect this marriage. To put it bluntly, if the landlord got married in Germany, but didn't go through the relevant certification in China, then it doesn't violate China law for the landlord to marry another woman when he returns to China. Because the landlord's marriage is only protected by German law, you have to sue or divorce to get Germany. Hehe, it seems that the landlord still took advantage.

In addition, German immigration control is strict, so it is difficult to get a German green card. It depends on the laws of the country where the child was born, that is, automatically possessing the nationality of a country. Some foreign countries have this provision, while others do not. Before you take the initiative, you might as well look at the relevant laws in Germany.
