Is it permissible to marry a woman without consummating the marriage for a long period, for the purpose of being able to speak with her until studies are completed and a job is found?

It is permissible to contract marriage with a woman and postpone consummation until she completes her studies or secures a job. After the marriage contract, it is permissible to be in seclusion with her, look at her, touch her, and travel with her. This is better than her remaining without a contract.
