In 2026, the official processing times for Schengen visas haven't changed - it's still the standard 5-7 business days, but in practice delays happen regularly. Your acquaintance ran into a real situation: queues at visa application centers are growing, especially in summer and fall when everyone wants to take a vacation in Europe. Plus, additional document checks might be required if something looks incomplete or raises questions.
What to do: submit your application at least a month before your flight to have time to cover yourself. When you apply, clarify the specific timeframes at your particular center - they can vary depending on how busy it is and which consulate's office it is. Some centers post information about current delays on their website. If your trip is time-critical, there's an expedited processing service (usually paid), but whether it's available depends on the visa application center.
