I want to know that will it still be necessary for me to sent my bank statement to the Germany embassy for schengen visa , whilst i received a invatation from the one inviting me from Germany ?
The bank statements have several purposes. One of them is to show that you have a stable job in your home country. This makes you appear more likely to return home at the end of the visa, and less likely to become an illegal immigrant. This is still necessary if you have an invitation.
