My baby and I got a visa from the French embassy but my husband's visa was refused. Can anybody can tell me if I can travel or not because my child is 2.5 years old? One consultant told me that immigration can create trouble for me because my child is too young, and how can I wondering with him (because purpose of visit is tourism).
If you and your baby have visas then you can travel. It doesn't matter how young the child is.
The only complication is that you may need proof that the baby's father has given permission for them to travel. Usually this takes the form of a letter from the father giving permission to travel. Depending on circumstances it may need to be notarized.
