If the Home Office determines that the original decision on your visa application should stand, you will receive a notification to that effect. In this case, you cannot request another review.
You can only apply for a second administrative review if the outcome of the first review uncovers new reasons for your visa refusal. With the second review, you can only challenge the new grounds for refusal, as indicated in your decision letter.
In general, if your administrative review is unsuccessful, there are three courses of action you can consider. The first is to reapply for the visa. It’s crucial to build a strong case and prepare the right documents before reapplying.
Another option is to make an appeal on human rights grounds. This involves arguing that the unsuccessful administrative review violates your fundamental human rights. However, this option is complex and only applicable in specific situations, so it’s advisable to discuss it with your lawyer before proceeding.
The third option is to initiate a judicial review. This involves taking the case to an immigration tribunal to determine whether the Home Office made an incorrect decision and, if so, to reconsider the matter.
