well.... to tell u the truth i dont really know or understand if and what do the visa offices look at in terms of hte docs that we send or hte emails... bcoz they do not acknowledge receipt of any docs and there have even been cases where they have lost docs inspite of sending email about the parcel sent.....
you can send email ... about your visa but i think it would not be much of an issue if you wait till they open your file and ask you for any further updates. there are basically 2-3 reasons that i am saying this -
1. even if you send email, you would not know if they looked at it so ... dont know if it will serve any purpose
2. when they open your file again and see that your visa is expired, i think they will ask you for update on that
3. dont know if htey link the email with your file immediately.
again all this is my assumption .....
also in a way, i dont think it would really harm in sending email with attachement of the visa renewal page ......
at least you can show them record later if and when required that you had informed them of the renewal....
dont think it would really harm... but i think wait for some senior member to reply to this.....
perhaps that they throw better light in this matter.
i hope i have not added to your confusion ......
actually how to deal with hte embassy is such a big question mark ..... coz we dont know if and what will push things in the right direction or what will rub them on hte wrong side.... its a big dilemma for all applicants i think ....
sad but true !!!!!
