"I can't do theatre in the US,' she says, 'because I don't have a green card"

This quote by Jacqueline McKenzie talks to the trouble of pursuing a profession in theatre in the United States without the proper documentation. It suggests that without a green card, she is not able to pursue her enthusiasm for theatre in the US. This is likely due to the reality that a green card is required to work legally in the US, and without it, she would be not able to obtain the necessary authorizations and visas to operate in the theatre industry. This quote likewise talks to the bigger issue of migration and the problems that immigrants face when trying to pursue their dreams in the US. It is a suggestion of the importance of having the proper paperwork in order to pursue one's dreams and enthusiasms in the US.
