Can I get an Australian green card without a visa or go to Britain from landing visa?

As long as you have a residence permit from any country in the Commonwealth, you can go to any country without a visa at all. However, Britain should be a country with strict entry control after the United States. I once had a friend from Hong Kong who went to England and held a British overseas passport. Because the immigration inspector suspected that he was inclined to emigrate, he was forbidden to enter the country and ordered to leave immediately. There is also an original European classmate who transferred from Switzerland to Ireland. He has a visa and paid all the tuition fees. He was still ordered not to enter the country and leave the country immediately because he was suspected of having an immigration tendency. Therefore, it is suggested that the landlord must buy a round-trip air ticket and indicate the specific departure date before going to the UK. Secondly, he can prepare the contact number of the local lawyer before going to England. In case there is any problem, it is better to pay a little lawyer's fee than to waste the plane ticket. Other countries should be fine. But the best way is to advise the landlord to consult the embassy or tourism bureau of the relevant country before going out, and prepare the corresponding regulations for backup before going out.
