Dependent visa query

Spouse name is already updated in both mine and wife passport....still do we require marriage certificate for dependent visa....please answer my query

Yes.  As the rules here do NOT require the name in the passport to be updated but instead, production of an attested marriage certificate.

Can I get marriage certificate from embassy?

Ask your Embassy.

Any news ? When  people having valid visit ( one year ) of bahrain can come ? Lock is partially over but any news about visit visa .

People are able to come on visit visa EXCEPT from red list countries.  There is no news about that and it is expected to continue for some time.
