Thank you for your response.
I am going to opt out so that one of my colleagues who specialises in Immigration can assist you because this is not my area.
I think you need immigration advice first.
The issue you have is that a court is likely to consider that your daughter is resident here. So even if she is granted an Indian passport - if you remove her out of the Jurisdiction then you could be charged with committing child abduction. My view is that you are going to have to make an application to a family court for permission to permanently remove your daughter from the jurisdiction. If your husband wont agree - then the Judge will decide if you can take your daughter on a test based on your daughters best interests.
