The Resident season 4 episode 4 is still weeks away from arriving on Fox. But, the network has been sharing updates on what's coming for several characters. For instance, Mina Okafor's (Shaunette Renée Wilson) storyline is going to be one of the major parts of the episode.

In The Resident season 4 episode 4, Mina realized that her visa is about to expire. This leads her in making a bold move for her future. It's yet to be seen what would be her decision -- whether leaving or staying in the country. Her situation comes with certain challenges.

Mina is one of the best surgical residents at Chastain Park Memorial Hospital. She's intelligent and doesn't care for anyone's opinion. Some of the doctors could help her deal with her current situation, especially since they recognize that she is a huge help in the hospital.

One of the doctors who'll be affected by this is AJ Austin (Malcolm-Jamal Warner). The premiere of the fourth installment saw the two sharing a kiss -- hinting at a potential romance. Now, they are heading to something deeper and their relationship will encounter several obstacles.

In a previous interview with TV Insider, executive producer Amy Holden Jones discussed what the future holds for both Mina and AJ. She noted that they're tired of them "dancing around each other," and they wanted to see them becoming a couple.

Jones said that Mina and AJ turned out to be "amazing together as an actual couple." Yet, the situation won't always be smooth sailing for them. The executive producer noted that Mina's immigration problem is their major obstacle -- something that will play out in The Resident season 4 episode 4.

It would be interesting to see how this situation would challenge the two. Their relationship is still new, but they already encounter a huge problem. This could test them how they handle the situation and whether their opinions on certain things differ.

Aside from Mina's storyline, The Resident season 4 episode 4 is bringing another medical case for the doctors at Chastain. The staff works together to diagnose a mother-daughter pair. Both of them have symptoms that make it hard for doctors to determine their conditions.

Devon Pravesh (Manish Dayal) deals with his mother's arrival, while Randolph Bell (Bruce Greenwood) deals with a fan who ended up needing treatment at the hospital. Meanwhile, Conrad Hawkins (Matt Czuchry) and Nic Nevin (Emily VanCamp) tries to figure out how to tell everyone their big news.

The Resident season 4 episode 4, titled "Moving on and Mother Hens," airs on Tuesday, Feb. 2, on Fox.
