The main goal of this contribution is to point out a few problematic spheres, where the generally accepted not quite correspond to the real situation. We emphasize that the path to the general knowledge of the culture of Slovaks living in Low Land is through the realization of research in widest context of theory in as many localities as it is possible. We present a view of the seven problematic issues, which in the context of the current research of Slovaks living in Low Land can be considered as relevant. First, there is the problem of the meaning of terms ethnic enclave and ethnic diaspora. Secondly, the consideration of degree of acculturation and the transfer of the meaning from term "language island" to term "cultural island". Thirdly, we are considering terms of ethno-cultural and ethno-confessional aspects of identity. The fourth problematic sphere is relation between local and ethnic identity. The fifth problem is the urban and rural environment and their contexts affecting acculturation in the minority sector. The sixth circuit is relation between ethnic identity and civic identity. Seventh problem is the minority policy in the European Union, its relative instability and undeniable impact on the acculturation of minorities.
