My Chinese inlaws might come to visit us in Belgium next year. However, they live in a very remote area and Belgium only has visa centers in Beijing, Shanghai and Guangzhou. As their official residence in Sichuan province, they should apply for their visa in Beijing which is very far away for them. Last time they came, they were able to apply for the visa by post which worked out quite well.
Now however, the Schengen visa requires a bio-metric identification (fingerprints). We would like to avoid them going through the hassle of traveling 2000km to Beijing just to have their fingerprints taken. Would it be possible for them to have their fingerprints taken in a nearby consulate of another Schengen country ? For instance, Germany has a consulate in Sichuan's capital Chengdu.
