YWAM England has said it had to learn several "hard lessons" to get the license back, and it's delighted with the Home Office's decision.
Youth With a Mission England was told on December 23rd that its licence to sponsor visas which allowed it to help missionaries come to the UK had been suspended.
It was after an inspection by the UK Visas and Immigration office found "clerical issues" with its administration process.
A YWAM statement said: "We are extremely grateful for this positive outcome, but admit that we have had to learn several hard lessons about our internal processes and our approach to record keeping.
"We are already implementing important changes to these areas and will work with diligence to live up to the high expectation of the UKV&I.
"During our last inspection, in September 2014, several issues were discovered during what turned out to be a tough audit. An action plan was immediately submitted and we believed that all of the issues raised had been successfully remedied.
Despite these best efforts, on 23rd December 2014 another government department, the Sponsor Compliance Unit (SCU) suspended our licence citing further additional breaches, some of which had not been previously communicated to YWAM via the SMU.
"After another round of extensive effort to address and allay these concerns, YWAM is delighted that the SCU have concurred and seen fit to reinstate our Grade A licence."
"The consequences for YWAM, should our licence have been revoked, would have been profound. Several hundred volunteer missionaries would have been told that they are no longer entitled to remain in the UK and would either had to leave or find an alternative sponsor. In stark terms, almost half of YWAM's missionaries (approximately 300 people plus spouses and children) would have had to make alternative future plans. It would have affected YWAM's activities, in-house training, social outreach and external ministries.
"We thank God that this situation has been so satisfactorily resolved and wish to offer our heartfelt thanks to all who have given support to us during this trying time. We have felt supported and encouraged and remain wholly committed to our pledge 'to know God and make Him known'."
At the time of the sanction, a Home Office spokesperson said: "We continually and routinely monitor all licensed sponsors. Where we find evidence that sponsors are not fulfilling their duties we will suspend or remove their licence."
