Most long-stay residents do not hold a multi-year visa; they renew permission to stay at a local immigration office every year. Each basis — retirement, marriage, family, employment or study — has its own financial and documentary test, and the office reviews it afresh every time.
Common reasons for refusal include bank balances that dipped below the required level in the seasoning period, mismatched addresses and missing household evidence. We audit your file a month in advance so there are no surprises at the counter.
What we handle
- Pre-filing audit of finances and supporting documents.
- Bank letters and statements to the office's format.
- Accompanied filing and follow-up visits.
- Calendar for the next extension, 90-day reports and re-entry permits.
