Hi,
I am facing the same issue- my letter states that I need to submit within 30 days, but I am travelling abroad for around 10 days. I am in a fix as to whether I should submit my passport now, or do it once I am back. If I do it now, the website says stamping could take around 15 days, which means my travel goes for a toss. On the other hand, i still have 4 days in hand after I come back to submit the passport- but I am worried whether I will get an appointment to submit at the local VFS within those 4 days. Please help!! Really in a fix!!
