Was claiming social welfare, One Parents Family also was working part-time, currently working
Two Part time jobs-
One Job- 15 Hour Contract
Second Job-20 Hour Contract
Also driving taxi part time
Reason for refusal
F-Finances shown have been deemed insufficient
PF-The granting of the visa may result in a cost to public funds.
Any suggestion re appeal.

What nationality is your current spouse?

Is your child an Irish citizen? If so, you may have a case under Zambrano.

If they have refused you on the basis of insufficient funds etc you have to prove to them that you have enough funds to support yourself and your family. If your spouse is reliant on social welfare, this will hinder the application greatly. You would need sufficient savings to cover a reasonable amount of time while you search for work or have valid written offers of employment and some savings.
