Nothing is more ambiguous then migration. It can be even admit that ambiguity is a standpoint of migration.
Migrant is a human being whose identity is changing all the time due to context of his life; migrant is on the move; migrant may evoke various associations; migrant decides and acts flexible when some internalized patterns become useless; reality becomes ambiguous when people of different background and origin started to live together. However, ambiguity itself is not acceptable, it is necessary to be unambiguous, classifiable or definable.
