Thanks for your question. I will try to help.
The ban has expired, so this is not likely to be an issue that you cannot get around, particularly if your application was based on EEA rules.
The problem is that you can only quality as an extended family member in certain circumstances. This is where you must be able to show that you are “dependent” on your bother.
Dependency means that you must be able to show that wholly or mainly financially dependent on your brother to meet your essential needs, which means that you would not be able to live where you are now without the financial help of your brother. If you are capable of working in your home country and supporting yourself there then you would not qualify.
If there are other family members in your home country then you would also not be regarded as “dependent” and could not therefore apply.
If you had a serious health condition and relied on the support/money that your brother gave you and there were no persons in your home country that could give you money/support then this would help you in claminig you are a dependent for the purpose of the EEA rules.
In summary, the ban is not likely to be the big issue but your eligibility in proving that you are a dependent of your brother is going to be a considerable issue.
My goal is to provide you with a good service. If you feel you have received anything less, please reply back. Please remember to leave positive feedback using the stars at the top of the page.
