Praise be to Allaah.
If you mean that the marriage contract has been done for you
and there remains nothing but consummation of the marriage, and that he
wants to consummate the marriage with you there, then there is nothing wrong
with that; rather it is something good and we encourage you and advise you
to go ahead, because it is better for you to be with your husband and it is
more chaste for you and for him, and will keep both of you further away from
fitnah.
Your family and his should announce news of the consummation
of the marriage everywhere and publicise it in the place where you are. It
is not essential for the consummation to actually take place in the country
where you are; rather that may be easier for you and it may be more
affordable to get married this way in the beginning, then after that you can
prepare your home gradually.
Shaykh Ibn ‘Uthaymeen (may Allah have mercy on him) said:
It is better for a woman to travel overseas with her husband
than to stay in her country; that is better for her and for him too. I do
not see anything wrong with it.

In that case he has to come and travel with you, or one of
your mahrams should travel with you to take you to him, because a woman can
only travel with a mahram. See the answer to questions no.

If you mean that you will travel to him without that which is
customarily called consummation, meaning that you would be travelling to him
thinking that you are married in the sense that a marriage contract has been
done but the marriage has not been consummated, in spite of all that you
mention, and that the actual consummation of the marriage will come after he
finishes his studies and gets a house and a job, when he can afford the
expenses of marriage and the consequences and costs thereof, this is a kind
of messing about and fooling oneself, and that is something that is not
acceptable at all.
This idea of yours seems to be based on the way you phrased
your question, “I got engaged on the basis of a contract” i.e., a marriage
contract, as some people call this period an engagement period, even if the
shar‘i marriage contract has been done.
But if that does not mean a marriage contract, then it is not
permissible for you to travel to him and none of the aims of marriage result
from that. Rather you should look at what your words really mean.
It says in Fataawa al-Lajnah ad-Daa’imah (18/69): Mere
engagement between a man and woman does not mean that it is a marriage
contract. Both the man and the woman may change their minds if they see fit
during that period, whether the other party agrees or not.
