I have some concerns about immigration thing.. I will be flying next month towards Vienna.. I have some few questions regarding immigration.. I have called them up last month for the requirements that they need for me to be able to pass the immigration. They just told me i just need an affidavit of support and invitation letter which was authenticated in Philippine embassy in Vienna.. I had the documents now.. As i scan the documents i noticed that the invitation letter isn't attached with the affidavit of support which has a sealed of red ribbon.. I have asked my partner then he told me the Philippine embassy in Vienna told him that the affidavit of support is enough.. He don't need to authenticate the invitation letter.. And last night i have exchange few mails with my friend who has a friend in Swiss.. His friend just flew last June and his friend told him to authenticate his invitation letter since that was the reason why she wasn't permitted to board.. she got offloaded since her invitation letter wasn't being authenticated.. And i have asked my partner but he told me the Philippine embassy in Vienna told him the affidavit of support and consent is enough.. Do you have any experience about this issue? And how does authenticated invitation letter looks like? :-(
