What are the current regulations for entering Germany? (quarantine, health checks, fees involved…)
Anyone entering from a risk area (as declared by the Robert Koch Institute RKI) has to quarantine for 14 days or show a negative test result for Covid-19. Test can be gotten on major border crossings and airports, sometimes free of charge (but one has to wait a few days for the results). For risk areas within the EU, the rules might differ (Please get informed!).
The situation may change at any time without notice, with areas being added or removed and rules relaxed or tightened.
Have there been visa changes recently? (new visas, cancelled visas etc…)
Most German missions abroad and most foreigner offices within Germany are still closed or on reduced worktime, so getting any visa is difficult.
Some types of visa, e.g. Aupair or Work Holiday, are not issued at all.
Is it easy to find work in Germany following the crisis? (working conditions for foreigners, quotas, new areas of work, incentives for remote working…)
Unemployment is up and due to the "Hire EU citizens first" rule, you can expect a difficult job search if you do not already have a work permit (e.g. by marriage to a German).
How would you view the local healthcare system in light of the crisis? (response to the COVID-19, how to get tested for COVID-19…)
Some shortcomings of the system became apparent due to the crisis, but altogether it is still one of the best in the world. Tests are now widely available and often free or covered by your health insurance.
Has anything changed regarding universities and schools? (safety for foreign students, changes regarding student visas or conditions…)
Universities mostly offer distant learning only. Schools are supposed to fully open again after the summer break, with strict hygiene rules (and the possibility of regional closures if hotspots show up nearby).
How is the real estate market following the crisis? (price, availability…)
The property market is very quiet, but prices have apparently not fallen (yet?).
Has the cost of living changed because of the crisis in Germany?
Apart from the token reduction of GST from 19% to 16% (or 7% to 5% on foodstuff and essentials), no change is perceptible.
Is there information relevant to expat retirees? (new measures for the elderly, visas for foreign retirees…)
See the visa section above. I think any such plans shuld be parked until the situation returns to some kind of normal!
How about lifestyle? Have there been major changes in habits following the sanitary crisis? (measures in public spaces, new habits to adopt…)
German's general aversion to masks has evaporated and they became part of anyone's day. Public life has still not returned to normal - especially cultural and social venues (e.g. festivals) are still vanishingly rare and restricted. These are such a big part of Germany's identity, that it currently feels like a country in hibernation.
