Background information:
I'm an European Union citizen temporarily living in Sao Paulo, Brazil.
I have a student visa (VITEM IV) that is valid for 7 months, starting from 01.10.2013 to 01.05.2014, which I cannot extend.
I need to stay in Brazil till 28.08.2014, when I have my flight back to Europe. (overstaying my visa with approximately 120 days)
I don't consider the period between 01.05.2014 - 01.08.2014 a problem (staying in Brazil with an expired student visa), since I can keep low-profile.
What is the problem?
The problem is that I need to take internal flights (Sao Paulo - Foz do Iguacu - Manaus - Salvador - Rio de Janeiro - Sao Paulo) between 01.08..2014 - 28.08.2014 . (with one of those GOL or TAM internal air passes)
Even though most forums say that when you take internal flights in Brazil they don't really check your visa status, but just the identification page of your passport, I can not risk that (since I'm not going to be traveling alone).
I cannot risk being denied boarding one of those flights. Ending up in Manaus and being the only one in my group not being able to board a flight to Salvador wouldn't be the nicest thing.
Fact to consider:
European Union citizens can only be in Brazil on a tourist visa for 90 days within a 180 day period.
What solution did I think about?
Around 26.05.2014 (therefore my visa will be expired for 25 days) go to Argentina for 1-2 days and then come back with a tourist visa (which will be valid for 90 days, therefore let's say the validity period would be 28.05.2014 - 28.08.2014, which will allow me to take internal flights without problems.
What are my questions?
Will I be denied entry in Brazil (therefore not being granted the tourist visa I'm hoping for) when I come back from Argentina based on the fact that I overstayed my student visa and just exited Brazil 1-2 days before?
Is it possible to obtain a tourist visa immediately after having a student visa? (Asking this due to being allowed to stay 90 days within 180 days in Brazil, as an European Citizen. Is it possible that they take into consideration my previous 7 months of staying in Brazil and not grant me the tourist visa because 90 days didn't pass in between?)
Can anyone think of a better solution that the one I came up with?
Unrelated question, but would be nice to know:
Currently I have a bank account at Itau. Will I have problems with it due to my expired visa? Does anyone check these things?
