Pros
Decent pay for the immigration field, good benefits and paid time off, a regular 9-6 work week, and exposure to the immigration field make the AP1 position a good way to start your career and get your foot in door of the immigration field.
Cons
Experience varies by team, but my experience is: poor on-boarding and training, the independent nature of the work together with high cubicle walls and few social activities means you have to make an effort to have social interactions, and the work is repetitive with varying levels that tend to the extremes (too much work or nothing to do). There is a sense that relationships are transactional and the firm does not invest in the professional development of APs. My overall takeaway is that repetitive work together with little room for professional growth and a stuffy, corporate environment results in low morale and means working here as an AP1 gets old real fast (less than a year fast).
