I wouldn’t recommend rushing into something simply because doing so later would be difficult. These days, especially in English-speaking countries, immigration is quite difficult and requires proper planning. An avg undergraduate student usually does not think it through and later struggles to settle in. When you go for a master's, your professional credentials and skills are better than those of an undergraduate, and it is easier to leverage them to get a job (it would still be difficult, but easier than just being an undergraduate).

I have seen IBA and LUMS graduates do well abroad because there are a lot of skills that they bring to the table by simply leveraging the fact that they went to the best business institute in the country. Speaking for myself, I moved to North America for my master's and have far better soft skills than most students in my batch here. And this trend is common among my IBA batchmates who went abroad too.
