WORK EXPERIENCE REQUIREMENT FOR NURSE WORKING VISA

Hi, Good Day! I want to ask help from you guys if someone from here knows about the work experience required for issuance of working visa for nurses.  I am already done with my prometric exam and my dataflow with positive response. I have 2years experience in homecare company in Qatar. My agency in Philippines said that our employer is still doing everything for us to have our working visa to Oman but we are already waiting for 1 month. Anyone here can help us regarding our query. Thank you so much
