A、Getting high skilled people. B、Promoting company’s technology. C、Finding enough employees. D、Increasing members of immigrants.

For several years, human resources director Pete Tapaskar says it’s been a challenge to fill all the jobs at his suburban Chicago-based technology company, [5] Getting high skilled people is still a challenge.
    Elizabeth Sue is principal policy analyst for the Chicago Metropolitan Agency for Planning, who studies Chicago’s recent immigration trends. She said "They are slowly moving into the south, especially Texas, and Atlanta, Georgia. [6]What we are seeing right now is a substantially decreased total of international in-migrations. Prior to the recession we were between 50 and 60 thousand most years.
    Now, since 2010, we’ve been at about 23- to 24-thousand international in-migrations on a net basis." [6]She says that dramatic drop—as much as two-thirds some years—contributes to Chicago’s overall still population growth.
    Tapaskar says there are many reasons why immigrants choose to live in Southern states instead of Chicago. [7]"The environment there is ideal for starting a business, could be the taxes there are low, and employers are getting a lot of benefits from the state government."
    But Tapaskar says one thing that could bring new immigrants to Chicago is increasing the number of work visas that would attract the highly skilled tech workers his business needs.
