This question used to have a straightforward answer. It does not any more, and the students hurt by that are the ones working from advice a cousin got four years ago.
Several countries have narrowed dependant rights specifically for international students in recent years. Before you build a family plan around a course, check the current rule for that exact course, because the answer now often depends on what and where you are studying rather than on your circumstances.
The rule that changed the picture
The important shift is that dependant eligibility is increasingly tied to the level and type of your programme. Research degrees and certain postgraduate courses tend to retain dependant rights. Taught master's and undergraduate study often do not.
The practical consequence is significant. Two students in the same city, both doing a master's, can get different answers because one is on a research programme and the other is not. This is not something you can reason your way to from general knowledge. It has to be checked against the specific course.
So the sequence is: check dependant eligibility for the course, then decide whether to apply for it. Not the other way round.
What it costs to bring someone
Assume every part of the application roughly scales.
More money to show. Each dependant adds to the maintenance funds you must prove, and the amounts are set per person. Canada's published funding table, for instance, moves from CAN$23,448 for a single applicant to CAN$29,192 for two people and CAN$35,888 for three. Other countries apply their own per-dependant figures.
More visa fees. Each family member is a separate application with its own fee.
More health surcharge or insurance. The UK's immigration health surcharge is charged per person, including dependants, at the student rate of £776 per year each.
Add those together and bringing a spouse and one child can easily double the cash you need to evidence. Families plan around the tuition figure and then meet this wall late.
Can your spouse work
This varies more than any other part of the question, and it is usually what decides whether the plan is viable.
In some countries a student's dependant partner gets full or near-full work rights, which changes the household budget entirely. In others they get restricted rights or none, which means you are supporting two adults on a capped student wage.
Find out specifically, for your visa category, before committing. A dependant who cannot work is a cost, not a contributor.
The documents that cause problems
Marriage certificates need to be in an accepted form, translated and often legalised, and the details must match your passports exactly. Bangladeshi marriage registration documents sometimes need additional attestation, so start this early.
Officers also assess whether the relationship is genuine and subsisting. Photographs, communication history, evidence of living together, joint finances. Couples married very recently, or married shortly before the application, get more scrutiny rather than less.
Children need birth certificates naming both parents, and where only one parent is travelling, documented consent from the other.
Honest advice we give most often
If money is tight, going alone first is usually the stronger plan. Get your visa, arrive, find accommodation, understand the actual cost of living in that city, then apply for your family to join once you have a real picture and a real address.
It is harder personally. It is far more likely to work, and it avoids the situation we see too often, where a family arrives together on funds calculated optimistically and runs out by month four.
Before you plan around this
Confirm dependant eligibility for your specific course and visa route, the per-dependant funds required, and whether your spouse can work. Those three answers determine whether this is feasible.
