Set a 6-quart electric pressure cooker to saute, heat the oil and cook the onion for 4 minutes; stir in the garlic and cumin for 30 seconds.
Add the chicken, salt, beans, green chiles and broth without mashing the beans, then lock the lid.
Cook at high pressure for 8 minutes and allow a 10-minute natural release before venting the remaining pressure.
Confirm the chicken has reached 165°F, stir in the corn and mash about 1 cup of beans while simmering on saute for 4 minutes.
Turn off the heat, wait 3 minutes and stir in the yogurt and lime juice.
