The study provides valuable insights into workplace discrimination faced by Venezuelan immigrants in Colombia. However, the use of a non-probabilistic snowball sampling method raises concerns about the representativeness and generalizability of the findings. Given the reliance on voluntary participation, there is a potential for selection bias, particularly from undocumented immigrants who may have avoided participation due to fear or distrust. How do the authors address the limitations of this sampling approach in ensuring that the results are reflective of the broader population of Venezuelan immigrants? Furthermore, could the authors elaborate on whether alternative or supplementary sampling strategies were considered to mitigate these concerns?
