Close ties over several years are a weighty argument in the balancing exercise.
Where close family or private ties exist over a longer period, this is a strong argument against a disproportionate entry ban. The authority and the courts must weigh your interest in family and private life against the public interest. The more established the tie, the higher the threshold for a long entry ban.
Document these ties carefully. Evidence of family, a shared household, work and length of stay gives the balancing exercise under Article 8 ECHR a concrete foundation.
