Can H4 get processed for spouse currently working in India

I am on an H1B visa. I plan to get a H4 visa for my spouse who is currently working in India. She plans to take a long leave from work, 4-6 months and join me in the US. She has no plans to resign from her current job.

  1. Will there be any issues in getting a H4 for such situation?

  2. Is it necessary to apply for leave beforehand and carry leave application? What needs to be done if she plans to travel later?

    >> No issue for any situation as far as the candidate shows the required documentation for H4.
  2. Is it necessary to apply for leave beforehand and carry leave application? What needs to be done if she plans to travel later?

>>This is H4 and not H1B so don’t bother about her current job or no job. If they ask her what she does tell housewife or current job. Bottom line it doesn’t make any difference.
