Visa issues delay England bowler Shoaib Bashir's arrival in India for test series
Bashir, who is of Pakistani heritage, is one of three uncapped players named in the England squad for the upcoming series, which kicks off in Hyderabad on Thursday.
"He's got a couple of issues with his visa coming through... we're confident on the back of the help from the (Indian cricket board) and the Indian government that it will sort itself out pretty quickly as well," McCullum told reporters.
People of Pakistani origin are required to submit additional details for obtaining an Indian visa, according to the website of the Indian High Commission in London.
In February, visa issues delayed Australian batter Usman Khawaja's arrival in India. In September, the Pakistan Cricket Board (PCB) wrote to the ICC alleging delay in issuing visas for the Pakistan team ahead of the 50-over World Cup in India.
McCullum said he hoped the 20-year-old spinner would join the rest of the team on Tuesday.
"We're hoping the news will come through today that his visa has been approved, then we'll get him to sink his teeth into this series," he added.
