My sister was living with her family in Muscat for the past 4 years. Her husband is doing business there now she wants to leave the country and come back to India but for some financial reason she and her 19 year old son did not renew their labour card for the past 10 months . Will there be a problem travelling out of the county? Can she and her son travel back to India without renewing the labour card? Someone please advice. Does she need to cancel her visa before this ? As she is on her husbands sponsor visa.
