Hello
@Maveina,
how nice that you turned to wefugees with your question.
There are two ways couples of different nationalities can organise their marriage and family reunion. Both procedures require some time - one way before marriage, the other way after marriage.
If the marriage is planned in Germany, there is a long lead time due to the procurement of documents, the checks and the organisation. Once all this is done, the future spouse will be granted a visa for marriage and a residence permit.
If the marriage is planned in the country of the partner, the formalities often do not take as long as in Germany. In this case, the time-consuming processing only occurs after the wedding. This is because the spouse first travels back to Germany alone and applies for family reunification. These formalities and checks now take the appropriate time before a visa is issued.
Unfortunately, what really does NOT work is to enter with a Schengen visa although you intend to move in with your spouse. The immigration authorities take this "deception of intent" very seriously and carefully. You then have to leave the country again in order to re-enter with the correct visa to join your spouse.
I understand that the long waiting period is difficult for you. But perhaps you can also imagine what "exceptions" to the entry requirements can do for the immigration authorities. Eventually, many people would get the idea to bypass the regular visa route via a visit visa. The various visa regulations are laid down by law and the immigration authorities are responsible for ensuring compliance with the regulations.
So I am sorry not to be able to give you a more pleasant answer. But for now, you can **** forward to your wedding. I wish you all the best.
Best regards
Gabriele
