A woman (in theory) can be sponsored by her husband to come to Qatar on a family visit visa regardless of whether her previous employer in Qatar provides NOC or not - provided that the previous employer did not file any case against her.

However, in individual cases, some people have faced problems at the visa stamping stage - due to the opinion of the specific immigration captain on duty at the time.

It is better to use a PRO who is familiar with various immigration captains.
