CapableCelery590 Immigration Officers has discretion to refuse entry visa exempt or visa holders. If they feel you are not a genuine tourist and are abusing the system they can deny entry. The MFA state this clearly on their website - a visa does not guarantee entry
Anonymous participant No idea. There is no universal guidance and each Embassy has their own interpretation and quirks. Probably even down to the reviewer too. The first person reviewing documents will not be a MFA but rather a "Local hire" that all embassies have. Different ones will ask for different things. One application may sail through while an identical one gets asked for more documents.
Anonymous participant As above I think it is for 180 days. KL has been asking this from the beginning. The workaround for the guy who posted recently (Austrian Embassy I think it was) was to say initial stay was for 1 month rather than 180 days.
