Renewal of family visa under old BD rule

Hi Every one.
I came here last year under family visa which states that the foriegn expat needs to have more than 250  bd to bring a family member.
My visa is supposed to be renewed this August and i am worried that if the new 400  BD rule will be applied.
My husband has less than 400 bd .
I read somewhere that this new rule doesn't aplly for those who already have brought their dependants under the old rule.
I would be grateful if anyone can help me here.
Thank u im advance

As far as I know, renewal should not be a problem. The rule affects new visas only. Unless something changes and things do change here day to day.
