The “first country of asylum” concept is defined as a country where an applicant: either (a) has been recognised as a refugee and may still enjoy that protection; or (b) otherwise enjoys sufficient protection including protection from refoulement. In both cases, the applicant must be able to be readmitted to that country.
The guidance reflects the change in rules and advises decision makers to consider of any relevant criteria apply:
- i) the applicant has been recognised as a refugee in a safe third country and can still avail themselves of that protection; or ii) the applicant otherwise enjoys sufficient protection in a safe third country, including benefiting from the principle of non-refoulement; or iii) the applicant could enjoy sufficient protection in a safe third country, including benefiting from the principle of non-refoulement because: (a) they have already made an application for protection in that country; or (b) they could have made an application for protection to that country but did not do so and there were no exceptional circumstances preventing such an application being made; or (c) they have a connection to that country, such that it would be reasonable for them to go there to obtain protection.
