My current Schengen visa (Multiple Entry visa issued by Netherlands) is expiring on 15th August . This was the 4th Schengen visa (which was valid for 2 years) . I am applying for the 5th time and my appointment date is on 2nd August in San Francisco VFS center . I have been visiting my sister in Netherlands every year on first week of September and my visit has always been for 10 days (So I have not overstayed my visa anytime) .
Can I reapply for my Schengen tourist visa 15 days before it expires ? I am planning to travel in Septemeber and my current Schengen visa expires on 15th August .
