Processing time for the Lost BRP replacement one time visa

[dexterous_1]

Hi All,

ANybody have any idea how long does it take to get BRP replacement one time visa when applied in New delhi , India. My wife have lost her BRP card while in India ..and we are planning to apply the one time entry visa to come to UK and then apply for the replacement BRP card from within UK. Does somebody have any idea how long does it take UK visa office in New delhi to process this visa. I understand that you can go to UK VFS center in Delhi on any day walk-in to apply without appointment by paying a fee. We are planning to use this service.
Also if anybody have any specific tips and something to take care of ...Please let me know.

Best ,
Kt
