[rangacharyulu]

I have applied for a Schengen by Spain embassy in oman for going to Austria. The visa details are as under:

ESTADOS SCHENGEN
TYPE C
MULTIPLE ENTRY
REMARK: VIS ESTANCIA

BOTTOM: INDOMEEST

Please confirm that I will have no problem in immigration at any Austria airports, I would be transiting through Frankfurt.

Need an urgent clarification.
