So if there are sanctions then they will let me know, right? I'm more afraid of shadow bans.

@jafarlihi Yes, but not necessarily right away. It may also be that your case is handed over to the court, in which case the court should inform you in writing about the outcome of your case.

Any penalty the OP should be prepared to contest. If the airlines have to delay or cancel the flight at the airport, it is a force majeure that under Visa Code the authority shall issue a visa extension free of charge. 11(6) AufenthG also mentions cases when the foreigner is prevented from leaving without fault.

@Tor-EinarJarnbjo I added an update to the post, please see the question.

In my experience, Germans are reasonable people. For all the fines, there is option to submit an appeal and if it is convincing, then matter will be dropped. There won't be any bans without informing you first. The informing can take some time though.

I think you meant to say the opposite of "not plan to leave before the last day of the visa validity." Also, if you submit an itinerary showing a visit of seven days and the consulate gives you a seven-day visa, you don't have a lot of choice in the matter.

@xngtng It may sound like OP is not at fault for not leaving Germany in time, but a single delayed flight is of course not a force majeure. And even if the airline he originally booked with is not able to get him out of the country before after the visa expires, OP could very likely yesterday have booked another flight to get out of the Schengen area in time. He may have been required to pay for that flight himself, but there is nothing in his story indicating that it would have been impossible to leave Germany in time.

@phoog Which is exactly why Schengen consulates regularly give you a visa for a few days more than you actually apply for. And I still think I ment to write what I wrote. I am not sure what should be wrong.

@jafarlihi It is a bit difficult to follow your explanation of what happened today. The first immigration officer unlikely said that you will have to write a report, but that they will have to write a report and it it is impossible for me to guess what the other immigration officer did when being away with your passport. I also don't understand why you didn't ask when getting your passport back. The immigration officer would not manage to get back to you, hand you your passport and leave again without you being able to at least say 'wait, I have a question'.

@Tor-EinarJarnbjo judging from some of the questions I've seen on this site, that practice is far from universal. I see now that I misconstrued "not plan to leave" because of the double negative "never a good idea to not plan to leave...."

@Tor-EinarJarnbjo It always seemed absurd to me but I have seen consulates issues visas with a few extra days of validity… and a maximum duration of stay tracking the plan that was submitted with the application to the day. This only helps if you also arrived later, not if you end up staying longer.

This is actually entirely consistent with a literal reading of the advice in the Commission's Handbook which only discusses the “period of grace” in relation to the period of validity. Regarding the period of stay, it simply says that “The period of authorised stay for one or two entry visas should, in principle, correspond to the intended purpose of stay”. Note that the OP didn't specifically say that his visa expired, just that he had to stay longer.

@Tor-EinarJarnbjo instead of blaming OP we should be blaming the German consulate for not issuing a visa that's at least 2 weeks long, precisely to cover any possible flight cancellations. The UK is much more sane for example and issues 6-month visas by default. Precise 7-day visas are plain absurd and have no reasonable justification.

If you're planning to overstay your visa, even a 1-day visa is more than sufficient. If you're not, getting a 2-week visa won't change anything

The US issues 10-year visas by default despite being far more paranoid about overstays

@JonathanReez I am not blaming OP, just describing the legal situation. I probably don't find the situation more sane than anyone else, but this is how German authorities act. At least they in practice distinguish between overstays caused by negligence and by intention.

@xngtng The handbook mentions flight schedule changes e.g. because of weather conditions or strike as force majeure. Weather conditions or strikes are of course force majeure, also usually affecting many flights. A single delayed flight is not.

@JonathanReez I don't disagree with the general sentiment but the UK or US don't actually issue visas for any duration of stay, that's at the discretion of the officer granting entry. The Schengen system is designed differently because of its multilateral nature. The crazy thing is that the OP probably had a 2- or 3-week visa and still got bothered by the 7-day maximum duration!

@Relaxed sure but even if you issue a single entry visa I don’t see any rational reason to issue it for less than 2 weeks at a time and allow a full two week stay

IMO it’s malice on behalf of the consulates
