US Citizenship and Immigration Services data released Friday revealed 60% of all completed H-1B cases received a Request for Evidence in the first quarter of FY 2019, which companies consider a high level that adds time, cost and uncertainty to the process, Forbes reported. Further, fiscal year 2018 data show H-1B extensions for existing employees were denied about 25% of the time for many IT services and consulting companies, even though such workers had been previously approved for visas.
