Dear collegues,

I have one weird (I think) question.

I have finished my PhD in the end of December/2015 and done a 6 months PostDoc at the same Uni. right after. When my PostDoc grant was over, I had to find a job as a teacher, but my passion, as I can imagine is the passion of many of us, is doing research. But, due some political/economical issues Brazil is facing now, the illigitimate government, that has taken power through a soft coup, is cutting almost all fundings to research. I have had two postdoc projects declined by one of our funding agencies, not because the project was bad, but because they say they don't have the money to it.
My CV is not the best thing in the world, so it will be very difficult for me to compete with others to take a grant in abroad Unis (even here in Brazil, where there is so little grant now). During my PhD, postdoc and now in my teaching experience, I have saved some money, that would be sufficient to survive by almost one year in a country like German, for example.
My wish is to go to some good research group, ask for some one year opportunity as a postdoc/researcher WITHOUT the need of grant or salary. I know it seems a bit odd, but I'm willing to do this sacrifice in order to improve my research abilities, network and CV.

Some questions come to mind:
- Will the head/leader of the abroad group find this offer weird, unusual? "Hey, what this guy is planning to do?"
- Is it legal?
- Will I have some visa problems, due the fact I won't have a fixed salary?

These are some question to start. I some of you could help me, I would be very thankful.
