Urgent:ICT Tier 2 Visa Extention for dependent

[SOURAV_SOMS]

Hi Team,
My Tier 2 Visa is due for extension in another 1 month, what is understood
in Normal Visa extension process it would take 8-10 week for decision and
during that time would not have my passport which can cause some extra
headache.

Would like to know is it possible while being in UK to apply for Visa
extension for me in priority and once I received my new BRP and Passport
would apply for my dependent (wife +son) VISA in Normal process, it would
save some extra money and I would be travel ready too.

please let me know the timeline to get back my Visa and Passport in
priority and what are the extra document required for applying dependent
Visa ( in extension )
