Me and my wife are applying for UK PLAB 2 visa

Me and my wife are medical doctors in our country and we have a five-month-old son.

Both of us have to take PLAB 2 in 2022, we have the option to book the exam on the same day and leave our child with his grand parents in our country as a home tie.

Another option would be booking 2 different dates for the exam with 3 weeks apart and tell the officer that one of us will go for the exam and the other will stay with the child.

We wish to go with the first option as it is easy, affordable and to prepare for the exam but we have been told that the second option would be more secure to get the visa for both of us.

Ps. PLAB 2 seats are very limited if one’s visa got refused, he would have to wait for months to get another seat.

THANK YOU FOR YOUR HELP
