[locaor]

Dear Forum members...

My Visa is expiring in start of June so need urgent Advise please.

Initially i got transition from HSMP to Tier1 and now i will be applying for extention under Tier 1 in first week of June. I got registered a Limited Company in September 2011 as a director and 100% shareholder. I will be claiming the points for earnings between September 2011 to 30 April 2012. The earnings i have declared are in the form of devidend transfered from my company account to my personal account on time to time basis. Documents i have arranged are.

Main Applicant:

Dependant :

-Tier1 Dependant Form
-Passport
-2xphotographs
-Maintenance ( I have maintained 1600 pounds for both of us for more than 90 days in same account. Account is in name of Main applicant)

I am not sending Degree as i believe it is not required though i have claimed points for Education also i am claiming points for English Language on the basis of my First Application.

Questions:

-Do i need to register myselft as Self emplyed with HMRC and pay class 2 NI?

-What earning i can claim points for i.e Net Earnings or Gross Earning?

-Do i need to send Mairrage certificate in case dependant is my wife?
