thanks Pete for your response...
here are some additional information of my status in UK:
Originally i'm having a two year work permit, fortunately i was appointed to a permanent post good for 60 months (5 years) as a member of the nursing staff in the hospital.
So my husband is belong to dependents of workers with limited leave to remain in UK.
We are able to provide the requirements as what stated in the WORKER DEPENDENTS VISA REQUIREMENT CHECKLIST - WITH LIMITED LEAVE TO REMAIN including the NSO marriage lisence.
We already submitted to UKVACS and after almost a week they returned the original with the letter from the Embassy that my husband is scheduled to an interview for the ECO to fully assess my husband visa application under the Immigration rules.
My concern is that if there's any other document other than what is stated in Checklist requirements that my husband would present during the interview?
and also if somebody have the same situation with us, can you share what might be the possible questions my husband would be dealing in ECO?
thnks
