How does a person from overseas become an ordinand in the Church of England?
If you want to be ordained in England, you would have to find a sponsoring diocese and convince them that you intended to stay long-term. Normally the DDO will not encourage you unless you have already lived here for at least a couple of years before applying. The road to ordination in the UK is a long and winding one, and a local vicar must first support your application to a diocese, which then begins to test your sense of vocation (calling).
